We did have exactly the same discussion when the DT transition was
started - this isn't something that people only just realised might be
an issue. There was a deliberate decision to focus on getting the
technology deployed to the point where it could be used as a straight
replacement for board files and accept that sometimes the results won't
be perfect and that we may need to rework as a result.

Can you tell a bit more about this decision? When was it made? Who
made it? How was it made public?

I remember seeing some of the discussion on linux-kernel at the time. I believe there was also a LWN article.
