That might be okay, but how does it help us get the Enchant support in
ispell.el DTRT?  We'd still need to detect when Ispell is used as the
back-end speller, no?

Versions of Enchant compatible with Emacs do not support Ispell as the back-end speller (I removed this support in version 2 of Enchant).
