/Adding/ a port is probably fine, since hosts can just use the default 
value or connect it to silence.

However, "adding" here really means "appending": the new ports must be 
added on to the end of the ports (by index). Definitely do NOT change 
existing indices for ports, that will definitely break a lot of things 
in horrible ways! It's not even possible to properly cope with that
