In much the same way that "self modifying code" is no longer a thing, "writing to the register memory without calling it a register" could also not be a thing, right - we do that sort of thing all the time.

So I'm just looking for a more in depth understanding of whether it's really the right idea to have n "phantom" addresses that don't actually map to anything as the core way that instruction streams are written...
