You are correct. My proposal only involves renaming functions, and
introducing a couple of new ones.

The goal of that proposal is not so much to change the Racket numeric
tower, but rather to clear up the confusion regarding what's an
integer and what's not, to align it better with what (I believe) users
expect.
