Comment (by goldfire):

 This has nothing to do with data instances. Datatype declarations that use
 `=` cannot also have a kind signature; only GADT-syntax declarations can
 have a kind signature. An empty datatype is considered to be in GADT
 syntax.

 So the bug here essentially just a thinko in that comment.
