I imagine maintaining compatibility across template-haskell versions
might be tricky. Prior to template-haskell-, I believe there
was no TH support for kinds, and class contexts were simply Types
rebranded (not supporting equality constraints). So some
not-inconsiderable sections of code would need duplication, or we'd
need to deal with CPP which always struck me as a fragile and
inelegant solution. Of course, I welcome the patches to prove me wrong
:) or well, if you just want to take maintainership yourself, the
package is really as much yours as it is mine at this stage.
