Now that TypeRep has a [KindRep] field internally, Data.Typeable should export typeRepKinds (alongside typeRepTyCon and typeRepArgs, which are currently exported) to allow users to access it.

Maybe. In the future I'm not sure we'll distinguish between kind and type arguments. I think a better solution would be for typeRepArgs to return the kind and type arguments.

In any case I mostly think you shouldn't be decomposing TypeRep at all. Are you? What's your use-case?

I'd be okay with combining kind and type arguments in typeRepArgs, especially since template-haskell does this already. I don't have a particular use case to cite, just the desire for parity with the other fields of TypeRep.

Once the type-indexed Typeable work gets merged in (#11011), this ticket will no longer be relevant, since neither typeRepArgs nor typeRepKinds will exist anymore.
