As long as we can make sufficiently clear that trying to use an unstable binding is going to be *very* painful, and not necessarily supported.
IOW, its okay to break DT setups with every release, as long as we tell people first. Well, at least you are being honest about it now.
That's exactly why we're starting to think about which bindings should be considered stable and immutable, and when that should happen. As Olof pointed out, we haven't fully enforced that yet. Preferably bindings will be marked stable very fast, but mistakes are always going to happen in early development. ABIs are very hard.
They are even harder if you cannot decide what the ABI is in the first place. Thanks, Richard
