I don't see it in the patch we are discussing, so, not an argument.

That's I agree with.
But somebody need to teach people how to do it better.

Depends on the maintainer and subsystem. This is arguable argument.
In my subsystems (let's forget about PDx86, where one per subsystem in
principle is not working by nature of the subsystem, but consider
others I'm maintaining) I prefer to have a possibility to track
changes independently on driver basis.

Semi-agree. That people can be self-organized into a reviewer gang and
try to learn together.
In any case, as for maintainers, the task has not only technical
aspects, but mentoring as well.
