The reality is the code already gets no chance to change on this regard,
considering the requirement that we need to maintain the interface
between kernel and DT as ABI.  The dts have been there like this for
10 kernel releases or so.

As I said from the beginning, though I personally take it as a churn, I
will still be happy take the change, as long as my upstream folks are
also fine with it.
