The build would be easier, no deps at all and could be shipped as part of the release since we control license. (license not an issue with capstone) And testing as mentioned.
The question if a third shared disassembler worth it, considering the relative small community.
I raised the Q, let's wait a bit and see...

Just want to mention that RV _can_ have same OP code for multiple instructions (vendor specific), binutils and llvm have the infrastructure to handle this, a quick peek at capstone made me think this might be an issue.
Thus task may not be as trivial 'add missing' instructions.
