Yes, and an out-of-tree arch port (as effectively these arches now are) requires constant maintenance (often subtle runtime breakage) to keep up to date with each new kernel release, which happens mostly automatically from arch maintainer POV while they're merged. Even without changes intentionally taking advantage of not having to care about these arches, it'll be only a few cycles at the most before a plain revert won't "just work". Cheers James
