Description
I figure it's not a priority. But by the time the engine itself is usable, and anybody uses it for making a commercial game, ray tracing is going to be far more wide spread.
Perhaps, with ray tracing which is all the rage in gaming these days, you could draw more attention to this engine to grow the community a bit faster, too!?
Death of Rasterization Not Only a Gain for AAA Games
I'm not under the impression that ray tracing is meant to co-exist with rasterization for long, not even in indie games. Rasterization is on its way out all together. Nobody will make a AAA game with this engine any time soon, but neither with the Unity engine that but, got some support for ray tracing, too, already. Well, it's coming. Bevy is left behind here.
Ray tracing is absolutely fantastic for indie games that don't use AAA grade assets. And that with no additional effort on the part of the indie dev. The power of such a renderer compensates for the lack of details given by high res textures and models. Think of Minecraft RTX(lower than low poly, lower than low texture res) and Quake 2 RTX(low poly).
Indie devs could make a Wolfenstein 3D clone that doesn't look like ass. Indie games like Stormworks, a game that is low poly, solid color style, and very dynamic in its nature (construction of vehicles), could make excellent use of the perfect soft shadows and GI. Shadowmaps like to run into limits here. And there is indoor and outdoor transitions.

The Competition
Also, there is the Unreal Engine 5. Some indie devs are willing to put up with the UE4 engine that already got ray tracing. But regarding the programming hardships of UE4, they may all disappear with UE5. To make things worse. UE5 can fully scale its high res models. It may be not needed to make low res models for every high res model anymore. This speeds up the asset creation workflow a lot for indies and AAA alike. Unity may actually loose its indie crown to UE5. Bevy is left behind here again by far, not even having RT.
Graphics Card Availability
According to someone at Nvidia ~3 years ago, Every AAA game would require ray tracing in ~5 years. So, that's ~2 years left from now. I can't find that twitter post now, but it's not too far off to my opinion. The 50 gen RTX cards could do that in ~4 years for AAA games.
Up coming consoles got ray tracing support, they are AMD APUs, AMD GPUs will follow very soon.
The only GTX successors to the 10 gen is the 16 gen that is a GTX variant of the RTX 20 gen. And those variant cards only come in 50s and 60s tiers. There is no 70s and 80s tier because GTX is already being phased out. This 30 gen (sadly not confirmed), or perhaps next 40 gen (likely), GTX actually may go extinct entirely and all Nvidia cards will support ray tracing so be RTX only.
The Nintendo Switch is the only console that doesn't do RT.
Gamers Owning Ray Tracing Cards
Gamers owning particular cards is of course always lagging behind to the actual availability on the market.
As the German saying goes that I once came across. I para quote: "Those who are sentenced to death live the longest!" - "Tote gesagte leben laenger". Because not everybody is after perfect eye candy. May just stick to what they got already. Though, they usually play on consoles, too, but consoles got a new generation with RT support up coming. And they are also in high demand now.
I still got my 1080ti, and many did skip the RTX 20 gen, because of it being very expensive and very slow with ray tracing in particular. That was the first generation and first gen is always slow and expensive. Now, the RTX 30 gen is out and are widely desired. And consoles are much more affordable. Those who don't care about the eye candy, they may still get it with the new XBox and PS5 at a very low price. Though, disclaimer, I don't know how fast the RT cores are on those AMD APUs. Unlike Nvidia, AMD lags behind with its upscaling technology. And actually everything...
I think that in ~2 years there will be the 40 gen release, that's bout the time one actually may release a game made with this engine!?
The 30 gen because of its low price, and high RT performance will saturate the ownership of ray tracing capable cards to a very large extend over the course of 2 years. Games like Minecraft RTX that unlike Quake 2 RTX, is a full conversion, and is played by an extreme large number of gamers, not only drive RT card sales but also increases the appetite for proper light/shadows/reflections in even non AAA grade games. World of Warcraft got an RT update recently.
