Why not? I'm pretty sure lockstep or not is a thing for both and TCMs 
seem to be a common thing.

And I don't really think System DT will not impact it. Though it's not 
well enough defined to say either way IMO.

But if Bjorn wants to take this, fine. I'm not acking it though nor 
worrying about it for any compatibility with system DT.
