You do definitely know the landscape then :)

The main Qt 5 maintainer is also Ubuntu's maintainer. From time to
time people from Ubuntu try to help us, with various degrees of
success, and here we are. Note that we do stress a lot what we think a
Debian package should be, and sometimes that clashes with other
distros expectations (and that's fine!).

Yes, but still not using Qt 6, so no need on our side to create more
work for us while not yet there. It would be much much easier if they
just used _stable_ API. And that's where we get back to upstream,
plugins, etc. Create _stable_ API and everything goes smooth.

No *key* package. As soon as we add private headers we gain non-key
packages trying to use them, and thus more man power at the time of
updating Qt.

No, see above.
