Comment (by RyanGlScott):

 Indeed, I will readily admit that I'm mostly parking this Diff here for
 Richard's sake (when he gets a chance to look at it). However, since you
 asked politely, I wrote up an (informal) specification of how I envision
 this would work
 [https://ghc.haskell.org/trac/ghc/wiki/Roles#Proposal:rolesfortypefamilies
 here], based on the conversations I've had with Richard about this topic,
 as well as the commentary in this ticket.
