The other procedures could take equivalence predicates instead of
comparators with no problem. The problem, however, is that the
deprecated functions are deprecated. First of all, you don't want to
use procedures in your code that may go away in the next iteration of
the standard. More importantly, however, implementations may write
warnings to stderr when you use deprecated procedures, which the
reference implementation of SRFI 125 does. You don't want this for
programs you want to share.
