No, it doesn't make sense to do it.

I worked on platform enablement for armv8, bringing all the ecosystem to 64 bit arm. Was an everest, so much code was expecting x86, lots of secret asm and other assumptions like memory model.

But once it was done, we did it again for riscv in no time, all the work was done, it was basically setting defines, maybe adding tsc/rdcycle (now rdtime).

Architectures don't really matter anymore, but also the overhead of architectures are pretty minor, riscv will probably win because it's basically free and single thread performance isn't as critical on client devices, lot of work goes to the GPU too, and servers do other heavy lifting. Qualcomm scared everybody too, and China is going their own way which means even more riscv.

Basically, nothing matters except cost now, we'll figure out how to run things on a potato, we've gotten good at it.
