> Most of the really interesting RISC-V chips include proprietary enhancements. 100% of ARM chips on the market include proprietary enhancements. I don't think that has any bearing on the adoption of the core ISA, unless you can point to cases where a decision was made to avoid RISC-V over licensing an ISA extension.

Isn't the point though that a lot of the enthusiasm around RISC-V is that it's 'free' and that's no longer the case if you're using a proprietary extension. Plus you're looking at much greater possible fragmentation than can happen with ARM?

  The big difference is RISC-V has been designed to handle that situation from the start. That's why the ISA is modular.

    There's is no modularity when my code requires a specific RISC-V model from vendor X.

    RISC-V is modular in the same way Windows or x86 is. Yeah, you can break up opcodes into groups and say there's some kind of probe to find out what groups are present. If your app needs that module then you're out of luck - it needs a different chip. This is nothing special and I don't see why it'd change anything fundamentally, competition wise.
