They haven’t been implemented (yet?).
Part of why I tried to extend the Starkiller firing to fit the full cue was in an attempt to make room for a government transmission offering belated assistance. Of course that idea would use some different shots, but in either case the Resistance scene would need to be manufactured. After doing the basic montage, people seemed to like that on its own so I didn’t go further in the idea of the transmission.
Perhaps the transmission could be added by removing the pilot reactions and instead inserting the ‘are you seeing this’ line. I just really like the wordless nature of the montage as it is, and the transmission would have to be quite good to be worth it.
But don’t let that stop anyone from trying this out - the attitude of the Republic is still the most problematic aspect of this edit in my mind, and something should be done to make it more helpful to the Resistance.
