Comment:

 This has nothing to do with visible kind application. This fails the same
 way:

 {{{#!hs
 data (×) :: forall (cat1 :: Cat ob1) (cat2 :: Cat ob2). Cat (ob1, ob2)
 where
   Prod
     :: forall
          ob1  ob2
          cat1 cat2
          a1   b1
          a2   b2 u.
        cat1 a1 b1
     -> cat2 a2 b2
     -> (×) '((a1 :: u), a2) '(b1, b2)
 }}}
