existential metatype. Until we model ExistentialMetatypeType as ExistentialType(MetatypeType), type resolution needs to look through the instance type repr when resolving a metatype. Otherwise, there's no way to distinguish between P.Type.Type, which is an existential metatype, and (any P.Type).Type, which is the static metatype of an existential metatype.
