I've only been able to keep track of the margins of the thread but I will 
admit that it seems surprising that we would use code licensing as a means to 
either enforce the exclusiveness of Plasma's artwork above and beyond the 
existing license for the artwork, or to prevent applications running on KDE 
frameworks (but outside of Plasma) from supplying an alternative KDE-authored 
QStyle.

On the other hand the major reason we would have needed a KStyle to have a 
license exemption in previous KDE desktop shells was so that third-party apps 
could better integrate into our desktop, not because we wanted applications to 
clone our style and use it outside of our desktop. So the extent that the 
plugin mechanism being discussed still allows apps to integrate into Plasma, 
it sounds to me like it's at least still doing what we'd expect, at least 
within our own shell.

Either way, we seem to have settled on the idea of Qt being wholly responsible 
for integration ties into the desktop shell (whether that's Plasma, Windows, 
something else), and for that integration by Qt to settle on a style. That 
approach is consistent with Breeze-the-style being part of Plasma instead of 
an upstream tier. Whether that's always the ideal approach to take is perhaps 
a different question, but I don't intend to open it here.
