X = no other extensions are allowed
Y = non-critical extensions MAY be ignored
If this truly is a technical change, then we should have an update doc. But
I'm just trying to minimize needless words.
Andrew,
Would an implementer need to know the difference when writing code based on the
current standards track RFC, or would they need to read the erratum?

That is indeed the key question. Errata (only) document obvious mistakes
in the original text, and are rarely read by implementers since few know
of there existence. By contrast an update will be flagged to them in
the metadata. In this case my assessment was that the matter was
technical and outside the scope of an errata a view I confirmed with
others on the IESG.
The update does not need to be a big document, but it will (if
published) have WG and IETF consensus for the change it makes.
