I understood that. My point was rather that in this particular case (a CPU bug that could be fixed via microcode, but AMD chose not to do so for certain CPUs), RISC-V wouldn't have been of any advantage, because there would be nothing to fix in the first place. Sure, one could introduce microcode for RISC-V and people have argued in favor of doing so for this exact reason, but the architecture was intentionally designed to not require microcode.
