I agree with this much.

Okay, you own that name subspace *at this moment in time*.  Who will
have the right to create names below that next March?  Five years from
now?  A hundred years from now?  Persistent uniqueness of names is the
core work of the URN group, and the consensus there is that DNS names
are a poor basis for any kind of URN (and what we want is exactly what
URNs are for: naming things).

If you are saying that the use of URLs as names is just a stopgap
until the URN registration stuff is sorted, then I'll accept that, but
be aware of the precedent you're setting with the initial "well-known"
feature names.

Nor do you own the host ""

In summary, I think URNs are a good fit, but not necessarily other
kinds of URI.
