Actually would it matter if it wouldn't be additive change? Since it would be diagnostic/special case. But of course it would be trivial for the vendors to add support for changing the communities this way, if this could be performed as a additive change you could offer your customers automaticly partial visiblity under DOS attack until it's resolved rather than 0 visibility. Not to mention how much it would ease pinpointing faulty/aggressive parties thus in long run it could have very positive effect for things like proper anti-spoofing configurations. -- ++ytti
