You probably want to make a clear distinction between Internet Drafts with
volatile SID assignments
and RFCs with permanent SID assignments.

Do you want early implementation (of modules using SID)  to be as painful
as possible or as seamless as possible?
Renumbering SID assignments may be extremely disruptive to actual
deployments.
Correctness of a SID file within a source document is not the same thing as
correctness of all SID files
across an entire administrative domain.

I agree the administration of SID assignments is out of scope for CORE WG
but punting
the problem to vendors or operators will not be good enough.
