Does that sound feasible? Yup, the big problem here is the whole DT as ABI thing - what happens in the code isn't so important but the DT is supposed to be stable. Or we could decide that this is one of the cases that's unstable in which case we should probably flag it up in the DT binding document if nothing else.
