Comment (by Iceland_jack):

 I discuss my use cases for this feature here
 [https://gist.github.com/Icelandjack/ae22c42b01c9be7e8a82f80bc8ab3f1c
 Encoding Overlapping, Extensible Isomorphisms] &
 [https://gist.github.com/Icelandjack/865476f2299a4916d4e237d0f8ed0119
 Rethinking Tricky Classes: Explicit Witnesses of Monoid Actions, Semigroup
 / Monoid / Applicative homomorphisms].

 Does it make sense to allow associated open kinds?
