Review comment:
No there could be a cache with the same `adaptable` but a different
"target" model class. For example, one could first `adapt` the request to
`MyModel.class` and then to `MyOtherModel.class`. So in the first case, the
cache doesn't exist and the model is of course not cached, but in the 2nd case,
the cache exists but the model is also not cached.
