Comment:

 As I thought, #12503 is very closely related to this ticket. Both this
 ticket and #12503 were caused by commit
 6746549772c5cc0ac66c0fce562f297f4d4b80a2 (Add kind equalities to GHC).
 While this ticket concerns using a reified type variable in a function
 declaration, #12503 was about using a reified kind variable in an instance
 declaration.
