Hi Ruben
I agree there still is the split/brain problem. To overcome this into deep things most often might be much more complicated than they look in the first moment.

Indeed, the “split-brain” problem is not so easy to solve, but we hope that the proposal addresses it in a different way:
The analogy is that right now, all VHF users, radio amateurs, air traffic control, emergency services, commercial services, etc. are in the same frequency plan where we just told everyone to use “110 - 170 MHz”. We argue that it is not expected for a radio amateur to want to talk to the police in these bands, nor do we have to force everyone to use FM so they can talk to each other, despite e.g. airplanes using AM.
If you had the above use case, you don’t try to find a way to allow all these entities talk to each other over the shared spectrum that they are allocated. What you do is try to give one part to ATC, to do whatever they want, one part to emergency services, one to radio amateurs, etc.
If someone is a police officer, a pilot, and a ham, they can either buy a single device that can support all bands, modulations, encryption, and features required, or you can have three devices, one for each use case.
That said, we think that making this “band plan” where every use case has its own part of the spectrum, and people can choose which one(s) they want to participate in, is the right choice moving on.
