Well I can think of at least one area where a little complexity would be worth it to reduce SW complexity. Optimal memcpy is often different between multiple implementations of the same ISA.
I would repeat the caveat that instruction sets should give thought to code generation in compilers.
Blasphemy ==> religion rather than reason.
