Having transient, non-permanent entries would break the RFC
1737 persistence requirements for URNs.
The paragraph you're referring to in RFC 1737 is (I think):
It is intended that the lifetime of a URN be
permanent. That is, the URN will be globally unique forever, and
may well be used as a reference to a resource well beyond the
lifetime of the resource it identifies or of any naming authority
involved in the assignment of its name.
It specifically states that the resource itself needn't be permanent,
just the URN. As long as the registry entries are given unique and
non-repeating URNs, a single registry would satisfy RFC 1737.
