Be careful making false equivalencies regarding formation takeoffs. One of the mistakes end-line CAF folks make is assume everything done in undergraduate training has to translate to the end product they fly (wrt formation landings getting the axe).
We are talking about undergraduate training environment here, volume is our mission. We don't have the ability to do a radar trail and suck our thumbs tied-in back and forth to/from the MOA. We'd be shut down formation sorties during MVFR days if we had to launch all singletons in instrument trail. Having to flight split in the MOA is a colossal ATC cluster nowadays as it is (we lose training on higher bingos to account for the long queues now if weather is below VMC drag mins, 4-ship training is about useless now in anything but CAVU wx days gas-wise), then you want to add a helen Keller drill on the departure end of the sortie because formation takeoffs are scary and good night irene.
UPT volume is just not equipped for launch windows where all T-6 and T-38 formation sorties launch in instrument trail. Most dangerous stuff I've ever seen in formation have been frustrated and belated instrument trail joinups where wingmen overtake lead in all dimensions. A complete football bat. Quarter of the sortie spent finding everybody, in a jet with a 1.1/0.8 UPT/IFF ASD.
Leadership recognizes this, which is why I'm willing to put money down we will continue doing form T/Os until we get onboard radar (not an emulator) in the UPT environment, which will be never. This business is dangerous, but people need to be careful not to miss the forest for the trees. Just because something doesn't specifically translate to what you do doesn't make it universally superfluous. Undergraduate training carries different risks than end-user MWS communities. That's why we do it on cheaper equipment.
