This reminds me of the Technology Connections fridge rant video. Similar arguments all around, the dumping effect of cold out of a vertical fridge is pretty crazy to watch with a thermal camera.
Seems like a generally good idea, the satellites already need to use star trackers, they need an almanac of what should be there so deviations need to be tracked.
I can entirely see the military perspective though, this is almost a direct challenge for any adversary that any maneuver you perform, we will know about it.
