Comment (by Iceland_jack):

 Replying to [comment:3 RyanGlScott]:
 > I do admit that I'm not a fan of having copies of every common `(* ->
 *)`-kinded datatype in `GHC.Generics`, …

 Agreed but is merging them a realistic option?

 > As another point of reference, the `trivia` package on Hackage calls
 lifted void and unit `Zero` and `One`, respectively.

 I like those names.

 As long as the name is consistent I'm happy. I have heard `Void`, `Empty`,
 `Null`, `Vacuous`, `Finalize` / `Initialize`, `Terminal` / `Initial`,
 `Naught`. Even `DevNull` :-)

 > So do you want to be the adventurous spirit that chooses a set of names
 to rally behind and argue for them on the libraries mailing list?

 Ack! Sure, I don't like dealing with the mailing lists though.
