Also I don't think I have said the very same exact things as Ilpo, unless I misunderstood something. > As noted in this chain, the plan for the next version is to include > ID2 in this quirk and instead of removing it in the simplify patch, > use a gate by the ROG quirk that is then replaced by a gate from this > quirk. Yeah but I also asked (perhaps too many times?) what's up with _ID1 and the whole reasoning behind this because as it stands now you are replacing X with Y, only to do Z without making clear to me the reason of Y, therefore Z also suffers from the same problem. > This completely addresses your comment.
