It’s not like GC isn’t a massive part of RVA23 - those are the basic instructions that handle 80-90% of all uses (including most of what CPython needs).
I’m sure one could do some optimizations on RVA23, but is it really worth it?

Bit manipulation offers up to almost 10% advantage.
Zicond allows branchless code which represents significant speedups.
There’s also serious gains to be had from crypto support.
I’d guess the rest aren’t as important to Python, but those are quite important.
