as a device creator the main issue is that SoC vendors maintain their own trees and their work doesn’t seem to easily make it into the mainline tree. this causes a lot of work on my end especially because there is no way to manage patches and bring over all necessary changes related to one subsystem from their tree to the mainline or other way around. this means that small companies can forget about using linux on devices unless they get lucky because other people already did the work. so the main issue i see is that it is too hard today to group changes related to a subsystem and too hard to manage patches. on the other hand the maintainers are open to bizarre and very involved changes like allowing rust in the tree. the effort this is taking could have been spent solving the above problems.
