I wonder if this usage is common enough to get an entry in this
introductory text.

> I also find the idea of having higher verbosity levels that aren't supersets of lower verbosity levels to be an anti-pattern, so I'd prefer not to see it in an official HOWTO. To my mind, verbosity levels should be checked with ">=", never "==".

I don't really understand this paragraph. Do you have an example to
compare with any of the examples in the attached patch?
