as far as I know, It's possible when adding or removing communities to
use wildcard '*' char. Not entirely sure it's possible when matching in
conditional if() statement... ❔

Specifically for conditional if() statements I am only aware of the
possibility of using XOR matching condition for BGP communities.

Looking into the Docs for Bird 2. It seems to be possible.
