Hello, I'm a custodian in the English Wikiversity, and I'm writing this behalf of the community. The current configuration of English Wikiversity does not allow custodians (equivalent to admins in other projects) to use mass-delete (nuke). It is only available to our bureaucrats in the current settings. Many Wikimedia projects allow their admins to use mass-delete (nuke), and we aim to restore this standard configuration.

The suggestion was made by myself. There were no objections, and 4 different custodians (admins) including myself have agreed. I look forward to hearing from the system admins.
