  Are you deliberately missing the point on purpose for rhetorical purposes?
I'm not suggesting it makes no sense for any architecture *except* x86.  I
hope that is clearer.  It certainly does make sense for anything with a big
set of idempotent numbered registers.

  But really, please: what's the use of being able to turn (for example) cx
into edi by adding a number to it?
