And this numbering is arbitrary and not connected to some hardware bits/register addresses at all? And in case we find some missing bits later we will just queue them at the end?

Your constant reminding of that on all the patches is getting old. Yes, this is what we agreed on two releases ago. And since there's already some very real bugs that can't be fixed because of that, there's really nothing to be proud of. Maxime
