There is an important difference between userland tools which have
kernel knowledge and drivers:

The user space interface is _STABLE_ - the kernel interfaces are _NOT_

That's the reason why out of tree drivers, filesystems ... are often out
of sync and contain more #ifdefs than code to cope with the dozens of
kernel versions.

SoC devices out of tree are a seperate steaming pile of ... I have seen
too many chip vendor kernels explode when you just try to do anything
else than run "hello world" on them.

I share Joerns distrust fully.
