Above needs to be in the commit message and actually linking to the relevant
forum thread.

in general sure, but I dislike the direction of the approach, as its again
moving in the same direction as e.g., pmxcfs, a single boolean flag for all
or nothing, which in practice will soon mean that's rather useless as its
spamming so much stuff that relevant things get drowned even for experienced
users.

More fine grained approach it both, the verbosity and the topic axis would
be much nicer, especially the latter as then a user could only enable
traffic-control related logs.

But just mentioning as this is a major pain point in pmxcfs that I get "hurt"
by frequently..
