As :fcc is controlled by Sieve extension mechanism, Sieve scripts need to be updated before :fcc can be used. This means that either users need to manually update scripts and/or implementations that would use :fcc automatically need to be updated. So older (nonextended) implementations are not affected by this extension. Does this help or did I miss the point you are trying to convey?
