I wish other Common Lisp implementations, particularly Clozure CL, documented their internals as well as SBCL does. Apple Silicon support has been a long-standing feature request, but nobody can really work on it besides rme himeself due to the sheer amount of "institutional knowledge" (and time!) it takes to understand CCL's compiler backend then add support for a brand new architecture. SBCL, on the other hand, was able to provide support fairly quick, possibly due to more maintainers, but I also think a big role that played in it was the fact lots of corners of the implementation are documented and it's fairly easily to get a hold of people actively working on the compiler (doug, stassats, et al)
