As there is strong consensus that the community should not allow to vendors to pick up codepoints on their own, i think that the best course of actions is to assign a fresh (not-squatted) number to this draft.

For what concerns 30 and 129, i suggest to mark them as deprecated with a reference to this thread.

I have to disagree.

It is not known what version of the wide communities draft has been
implemented. This code is deployed in the wild, there are no guarantees
that those routers will ever be upgraded.

I think the -wide- deployment effort will shoot itself in the foot by
using 129.

Kind regards,

Job
