We would prefer not to manage a separate registry w/internally-declared registration procedures ourselves, and have no mechanisms for designating experts, handling appeals, etc.

I am pretty sure that the YANG community would watch any depletion process very intently and create another RFC well before the 1000000 SIDs are consumed (assuming that RFCs are still being made when the depletion finally happens, which may be centuries from now).

I am maybe a bit more concerned about the 0..59999 range set aside for the RFC Required space running out, which could happen within a decade or so.  So maybe we should indeed increase the cushion a bit there.

I made a PR:
https://github.com/core-wg/yang-cbor/pull/163
