Tbh, I understand the problem. There are just so many volunteers for making newer developments work on every platform. Streamlining the development and easing the load on the volunteer devs seems a good idea. Having that said, it’s ofc a pity to drop support for devices. At least the LTS kernels will support the current support for a while and the vibrant Linux community will find a good way to work it out, I have no doubt. Many machines, in particular old ones, run with very old kernels to begin with…
