I can see some reasons: * if you want to support the development of RISC-V as an alternative to x86 Arm /have some preference for not supporting x86 or Arm. * if you are writing code generators, you may find RISC-V easier to generate code for. If you don't care about these, then I would agree, keep using what works best for you.
