The original motivation for Indexed REMAP was to mitigate the need to add an expensive `mv.x` to the Scalar ISA, which was likely to be rejected as -a stand-alone instruction. Usually a Vector ISA would add a non-conflicting +a stand-alone instruction +(`GPR(RT) <- GPR(GPR(RA))`). Usually a Vector ISA would add a non-conflicting variant (as in VSX `vperm`) but it is common to need to permute by source, with the risk of conflict, that has to be resolved, for example, in AVX-512 with `conflictd`.
