I know this is outputted to IRC, so it should be rather easy to implement a player feedback (other than the receiving target).
You can use the console to rebind it, but again should be somewhat easy.
You can do this anyway, its in your config files in UDKGame, just take a copy of them before doing an update/re-install, but know that some files cannot copy over without causing you issues. Such as UDKRenegadeX.ini (which holds version information).
Your section for "Friendly Airstrikes" (Assuming a non-commander power version), this would be different to how they behave, since GDI have directional airstrike.
You could implement it for Nod though, since they just hit an area, not a line based attack like GDI.
Otherwise, should be somewhat good QoL changes
