I've posted RFC: Resolving issues related to extension versioning in RISC-V <https://discourse.llvm.org/t/rfc-resolving-issues-related-to-extension-versioning-in-risc-v/68472> which discusses some related issues (I think it complements this patch, rather than anything being blocking or suggesting a contradictory approach).
