I don't completely agree with this.
We have lots of partition layouts in the upstream DT.
Moreover, this is the default layout and changing it, will
result in incompatibilities and also might result in device "bricking".
Those can be changed from the boot loader in case you need those
the other way around.
Another question of mine is, why should you?
