[AMD Official Use Only - General] Mike, Agree. This can be mentioned on the Wiki page. Also, this would require the discussion between maintainer and contributor. I would say maintainer has the responsibility to make sure an arch folder is only created when necessary.
Do you agree with the arch concatenate solution for arch folder? That means IA32_X64 instead of X86 (I am fine with this)? However, there is one scenario. Assume there were two arch folders IA32_X64 and RISCV64. Then ARM shares the code with IA32_X64, we may rename IA32_X64 to IA32_X64_ARM. Although the directory naming is not real a problem to the build, a separate ARM folder seems easier? Or we can just allow this kind of folder naming structure, however we let maintainer to make the decision?
