Auch!
How is that for being able to count on Qt as a stable platform? 
QGraphicsProxyWidget has been introduced in 4.4, released in the first 
half of 2008. That is less than 3 years ago. And now, you tell your 
users that what they have come to rely on is suddenly not supported 
anymore? There is no "depricated" label to be found for that class.

What are the promises made by Sebastian Nyström at the 2010 DevDays that 
investments in the desktop area would not go down worth, if this is what 
happens in practice? [1] Can we rely on QML being supported three years 
from now, or will we again need redo our components in the next great, 
yet immature, Qt technology again to expect to work against supported code?

I really love working with Qt, but I really don't like the way users 
with existing investments in Qt seem to be left in the cold because 
their little corner is not the next hot thing any more.
