Jakob Heitz responded to the suggestion to extend the reserved Global
Administrator values, but for some reason I can't find that email in the
IETF IDR archive, I've copy+pasted it here:

draft-ietf-idr-large-community-11.txt
No new text is required to cover this: 23456 is not an ASN.
Besides, if anyone were to put it into a large community, no harm
would be done other than what would happen if any other unassigned
ASN were used.
About reserving values, we don't reserve values because the values
are unusable, but because we may want to use them for other purposes
later. There is no need to reserve another value. 3 is more than
enough.
Thanks,
Jakob.

WFM, but please get your chairs to chase down why the message didn't
make it to the archive.
It shows up in the other archive:
https://www.ietf.org/mail-archive/web/idr/current/msg17255.html
Thanks,
Jakob.
