some time ago you also wrote in this thread:

In other words: this is a discussion about compatibility with the world outside of Linux.
And compatibility can not be achieved by decisions about Linux implementation details,
even if Linus is deciding. He can just decide to stay incompatible (but then it should
IMHO be a general decision and not case specific).
So I think we should follow some basic design principles, if they exist (which I don’t know),
to have this compatibility. And then adapt the Linux implementation (using the KISS principle).
Anyways I have not yet seen any comment from the DT people or did I miss them?
