err, right.

but quite frankly, i call foul on that one and some other items in your
list. you had some frustrations as a packager, but that's just part of
the job, and doesn't authorize you to impose requirements that make it
basically impossible to employ qt as a bootstrapping device for a qbs
ecosystem.
