Re: [RISC-V][tech-os-a-see] [RISC-V] [tech-unprivileged] Direction of Identifying Extensions

Greg and I did discuss having Unified Discovery (UD) description macros for profiles, e.g. an RV22A bit that indicates support for all of the individual extensions (and option value ranges) required to meet the profile requirements.
This was in addition to, not replacement of, all the individual requirements, so you'd still have to set the values for each individual required extension.
The idea of have a macro "bit" (perhaps) for a union of different features, and a way to carve out/remove (and probably replace) some specific extension or option is an interesting one, but sounds fraught with possible weird corner cases.
