…0524) These lemmas only apply to `Fintype.ofIsEmpty` and `Fintype.ofSubsingleton`, but they're discrimination tree keys match any `Fintype.card` application. This forces Lean to attempt to unify the variables too often, especially because unification problems which introduce metavariables don't benefit from the same caching mechanisms.
