Comment (by Iceland_jack):

 Yes, it would even be possible to have listed instances depend on whether
 `print-explicit-kinds` is enabled or not: i.e. we only list the instance
 if `*` appears in the output (having instances depend on flags is weird,
 the current behaviour may be preferable).

 Another idea is to treat `TYPE` as a special case and temporarily show
 explicit kinds when its instances are printed regardless of flags.

 The connection between `TYPE` and `*` may also not be obvious to users.
