Absolutely, though I myself don't wish to undertake it at this point.

I think that would be a mistake, though of course I can't prevent it.
I believe the use of an ordering predicate is fundamentally more
aligned with the Scheme way of doing things than a comparison predicate.
I originally proposed some proto-comparators that only did equality; Mike
Sperber pointed me to SRFI 87, and I ended up incorporating everything
in it rather uncritically.  However, it should be easy to rewrite SRFI
114 on the basis of SRFI 128.

Good.
