I work mostly with a fork of LLVM (https://github.com/apple/llvm-project) and do care about the usability of `cmd` as a shell (however, it is significantly behind but is working on updating to a more recent version). I think that Swift is a large enough consumer of LLVM to consider testing that before declaring this feature removed.

Thanks for mentioning this.

Given that `cmd` as a lit external shell appears to be have been unusable since April, 2022, how is that fork relying on it?  Is it farther behind than that?

Fixing the remaining problem with `cmd` appears to be straight-forward, so I'm fine to do that.  However, how hard would it be to use lit's internal shell for your use case?
