More accurately, you said so and I chose not to dispute it. That
doesn't mean I agree with you.

Are you going to argue that every Scheme must, except in extreme
circumstances, support the whole numeric tower? So much for Bigloo,
Chicken, SigScheme, Scheme 9, SCM, Dream, Psyche, and Wraith. (Not all
of these are R5RS, but the tower has been around a long time.)

It borrows from R6RS, yes, but it also borrows from CLHS. It is, in
plain language, a revision of R5RS.
