OK, sounds fair, whatever the solution is implemented.
I was using codesearch.d.n and there are 83 that match "qdoc":
https://codesearch.debian.net/search?q=%5CWqdoc%5CW
Probably not all of these will actually use it for building (maybe
they will only test if available, and will generate an empty package
or something), others might do it only on -indep as Adrian says.
Almost certainly it will break some package.
At that point we can intervene and explain to maintainers, or provide
patches, for them to build it as -indep, so it's a win also for the
wide Debian project (building -indep when possible, saving resources,
etc).
