Yeah unfortunately there isn't really a great place that lists all the extensions with links and ratification status.

But anyway there is a sort of standard set of extensions that "application processors" (I guess CPUs that want to run precompiled code) should support:

thanks, so for something like the reviewed board above, how would RV64GC map into one of those profiles, or set of supported instructions?

RV64GC expands into RV64I + M + A + F + D + C. The CPU in this board also has the Zba and Zbb extensions (which together with a couple of others make up what was originally envisioned as the "B" extension, but it was decided to split it up).

RISC-V's wiki specification status page[0] is about as good as it gets.
