There is that general (much bigger) issue with fragmentation as well. But that's mostly seperate from 'I also need to stick a devicetree on my boot media'. (I do know the pain of non-mainline linux SBCs, and I make some effort to avoid it now: even if it means using old chips, I'll very strongly prefer one with mainline support, note that raspberry pi is also pretty behind on getting their support upstream, even the pi 4 is still lagging, and the pi 5 isn't even usable. They just have some vaguely decent support for their fork)
