Comment (by goldfire):

 Thanks for taking this on, Ryan, but I'm unconvinced that GHC needs built-
 in support here. What's wrong with using `th-lift`? I mean, I agree that
 in theory, `DeriveLift` would be nice, but it's Yet Another Thing. If
 something can be done well outside of GHC, I think it should be. A common
 argument here is that if a feature is built-in (as opposed to requiring
 TH), then users don't have to use TH. But that argument falls flat here,
 because users are clearly already using TH!
