	I was talking about the trivial case - prevent a user from creating a

at least 90% of use cases IMHO.

they are fundamentally different namespaces is nothing but a hinderance
to users, and fudging an aggregation of these fundamentally different
namespaces should be both possible and beneficial to most users.
