Arnd, you've made you preference clear and this note has been added
specifically for this reason, and transparency. 

I've exposed a technical reason for my choice. Going with the 'default'
approach makes things more difficult in the long run for those
maintaining this platform, me included.

The trouble of having to coordinate changes in 2 different subsystems to
have an appropriate configuration and the pitfalls of using 'default'
outweigh the extra review trouble of using 'imply' ... especially when
the pitfall mentioned in documentation is explicitly addressed in the
description.

If there something wrong with 'imply' existing and being used, maybe the
Documentation should be updated to reflect this, or the support be
removed entirely.

ATM, it exists and it makes things a lot easier for me to support and
maintain this device.

This all started with a maintainer request to move some resets away
from clock. More requests have been added along the way, making things
more generic. I'm more than happy to have contributed my effort and
time on this and I don't think anybody's time has been wasted so far.
