I believe it is a real implemented feature.

On an x86_64 Linux kernel you can run x86_32 binaries which have a completely different set of system numbers and somewhat different semantics. I presume a similar arrangement can cause syscalls to be routed to a "CloudABI" set of systemcalls.
For the most part the sematics that Capsicum allows will be fairly uniform thanks to Posix. I haven't looked into the specifics of the code to see how many "Quirks" need handling.
