The issue isn't so much that you can't place classes in separate registries (namespaces) to keep them from clashing, but that classes in separate registries apparently have no way to interact with each other. This makes it very tough to inherit from the identity classes or even reference an identity class unless you are willing to put your whole app in the identity registry, which kind of defeats the purpose. A couple relevant threads:

"Fixing" it means allowing objects in separate registries to interoperate.
