A challenge with any new transitive (extended) well-known community is
that until the thing is standardised, people don't know what to filter
and chances are the thing can just pass through anything. There even are
BGP implementations in which you cannot delete unknown extended
communities, so you'd have to wait until you receive a software update
before you can scrub those specific new types.

I don't encourage blanket community scrubbing either. So we have to be
careful when introducing new codepoints associated with specific
semantics.

Kind regards,
