rva23 is pretty friendly.

Needn't use the long thing.

Yea, but remove any one of the extensions and you have a distinct arch with a name that is basically just as confusing.

The point I wanted to make is that nowadays a lot of the extensions do not have such a nice (semi) easy to remember name.

RISC-V went wild with the extension naming in the past few years with the recently ratified extensions. The original extensions are all clubbed to be labelled as G.
