Yes, of course I've noticed (how can someone to not notice?).

Yes, the situation did improve, that is correct.

Currently, SoC maintainers have a separate branch of board specific
patches and it is kind of a burden that they live with and push it
to Arnd.
What I'm trying to propose here is another level of maintainership.
Which would accumulate board specific stuff (not SoC specific) and
push it to Arnd directly with no need to involve SoC maintainers
(may be only for Acks on SoC stuff).
Despite all the efforts to move to DT, there is still much work
must be done and IMO the board files aren't going to disappear in
the near future (say 2 years?). Meanwhile, my proposition can
lower the work load from SoC maintainers.

There is a possibility that my proposal will not serve well,
or may be it will?

Before making any decision, I want to make sure you understand
what is that I'm proposing here.
