first of all, I don't think starting off an email with "QML: a packagers
nightmare" is a good-faith way to start a discussion about something,
especially given the issue presented has little to do with QML as a
technology and is rather specific to the projects involved.

Furthermore, kwin is not a framework, it's part of Plasma, and
dependencies between Plasma components are generally fine. That there is
a circular dependency between plasma-workspace and kwin is not good and
should probably be addressed somehow, but the severity is somewhat lower
given the cycle doesn't exist at built time.
