So, did anyone try to push a Qt app to the store, or have an official statement of either party?
Yes, there are qt demo applications in there. See the following examples:

and
https://itunes.apple.com/us/app/qtquicksand/id666273528
This answers your question and concern I believe. As for further information, Qt 5.2 will even come with more support for this mobile platform. Although, I am not working on this port in the Qt Project, but I see that as a developer that 5.2 seems to support a lot more.
For instance, v8 has just got replaced by the new shiny v4 engine which will allow the proper QtQuick2 delivery for this platform.
That being said, the Apple Store will not allow dynamic libraries for runtime loading, so you will need to link statically.
