Comment (by simonpj):

 Hmm.

 * I think that there's an easy source-code workaround for #14209
 (correct?), so fixing it isn't that urgent.  Leaving 8.2 alone won't block
 anyone's progress.

 * While I doubt the patch will break anything, it is a non-local change so
 I'm not 100% confident of that claim.

 So I'd be inclined to merge it only if we can do a solid smoke-test
 against all of Hackage/Stackage to confirm the "no-break" claim.  In the
 future that'll be easy to do; I'm not sure how hard it is today.
