We've had this discussion a number of times. You forced the backward compatibility onto us without any warning, and now we have to support it. And it's already a pain. Maybe ARM can fix that problem by just assigning more engineers to that, but that's not something we can do. The fundamental difference is that we're mostly just a bunch of spare time programmers working on this platform, with a partial documentation for the controllers, at best. You forced me to ask these developpers to work on their weekends and evenings on some crazy corner cases to maintain the backward compatibility. And honestly, both from a technical and human standpoint, I definitely understand if some of them are just leaving and don't want to work on it anymore. I would probably do the same in their position. And having to ask that for companies like ARM or SUSE just makes it more frustrating to be honest. So there's simply no way you have forward compatibility while I'm there. Or you manage to convince all the ARM maintainers and enforce that compatibility for all the platforms.
