That's helpful information.

We should wait for anyone else with information to weigh in, but if it's
correct that the other experimental attributes haven't been implemented and
deployed in a way that would provide guidance for standards-track use, I
think defining PADDING in this document makes more sense to me than adding
a downref to an experimental RFC that we wouldn't consider if the reference
was using anything except PADDING.

Thanks,

Spencer
