Yes. These things can wait until later. But we could prepare for this
by handling unknown URIs diffrent from known URIs. That has an
implication on how to generate URIs from anonymous resources and how
to handle those URIs with foreign origins.

This leads to that the generated URIs doesnt have to be globaly
