Comment (by RyanGlScott):

 I've responded to comment:16 at
 https://phabricator.haskell.org/D5229#inline-42631. (The code is very
 nearly correct; you just need some minor tweaks to make it compile).

 Also, thanks for adding a test case for this! Once the VKA patch lands, I
 can look into tweaking `GeneralizedNewtypeDeriving` itself such that it
 generates code with visible kind applications.
