It doesn't bloat.  It reduces.

And it's not a forecast.  This stuff is well-known already.  It's here
today.  Look at how similar AVX is to SSE and how similar SSE is to MMX.
There's tons of redundancy in the existing specification.  It's
non-orthogonal and cumbersome to maintain.

Honestly, we really don't want to prepare for the future and make things
simpler for the average developer in the process?  Especially after the
discussion about a year or so ago where people seemed at least
interested in the idea?

At least allow me to present the work without facing a crowd that's
already made up its mind.

And I'm still waiting on a patch review.  If no one has objections I
guess I will start committing.  I'll wait until tomorrow though.
