The argument is that DT is a stable ABI we must never change it once
it hits mainline.
This leads to not accepting patches into mainline until they are
'stable'.
Whihc leads to vendors shipping code in real systems to real customers
with those out of tree patches. (Deadlines are a bitch)
The vendors are now forced to treat the DT as an *UNSTABLE* ABI
because they are shipping non-mainline DT schemas and plan to upgrade
to mainline someday.
Now the vendors no longer value DT as a stable ABI.
So, why are we making argument #1? Seems pretty self defeating to me.
