Ah that's the conflicting part. I'd say treat all -v and -q equal, so modify the bconf.verbose variable, and it's straightforward to document. Some time in the future we should also issue a warning for 'sub-command -v'. The order makes it unintuitive so btrfs -q command -v is going to be the default verbosity. We can't ignore the sub-command part, and making it conditionally work in case there's no global verbosity setting is kind of complicating it. So let's take the simple approach, maybe we'll have second thought on that before release.
