I looked this up as well -- since it's a "MAY", I would agree that the change probably does _not_ technically violate the RFC. While it does mention the "undesirable consequences" of people using other prefixes from deduplication problems, e.g.,

I think the docs are auto-generated, so I think the change in init.h is probably sufficient? https://gitlab.com/muttmua/mutt/-/commit/9c1ce59874ce1c8e97d0c5bd71847596dafb1d50 w
