I don't understand why this proposal in any way benefits SRFI 105-based
code.  Can you explain further?

I don't see why.  The idea of <? and friends is that they are generalizations
of < and friends (also string<? and friends, etc.); that is, they are
predicates.  Rather than having the function be either a predicate or
a predicate-maker, my idea is to separate the two purposes, so that
in one case we always get a boolean result, in the other case a procedure.
