In some cases it could be painful to maintain device-tree compatibility for platforms like NVIDIA Tegra SoCs because hardware wasn't modeled correctly from the start.
I agree that people should use relevant device-trees. It's quite a lot of hassle to care about compatibility for platforms that are permanently in a development state. It could be more reasonable to go through the pain if kernel required a full-featured device tree for every SoC from the start.
We absolutely should support the newer kernel with older device tree case, what's less clear to me is the new device tree with old kernel which is applying LTS updates case. That does seem incredibly specialist - I'd honestly never heard of people doing that before this thread.
There was a precedent in the past [1].
