I can understand that in atom's case. That's why I'm fine with the
section mechanism being applied there. At the beginning I'd thought SOF
is already prepared to take over /atom/. As that's not the case, to ease
the transition, dynamic switch could prove useful.

There are no circumstances under which Intel recommends distros to try
to convert out of catpt though. Don't believe aligning all the drivers
to some general idea just for the sake of aligning is a good move.
That's why drivers have their own specifics in the first place -
their complexity and performance could have been negatively impacted
otherwise.
