No. Besides what René said, note I did not say this is the objective. I said 
it's known to be broken. It can be unbroken at any time, given enough people 
interested.

I do not plan on testing static linking until very late in the cycle, and I 
certainly will not test that on Windows.

Depends on your criteria for popularity. There are many criteria, like "number 
of deployed installations", where other distros take the lead.

Yes, there are plans. There should be a solution for using Qt Quick on 
desktops too.

Well, Apple and Microsoft broke that promise long ago already. The widgets are 
hardly enough to continue following the style and look and feel of their 
desktop platforms. One codebase without #ifdefs will not look completely 
native in both at the same time. They are now too different for the same 
widgets to be completely native.

If you accept that, then you're forced to have adapted sources for each 
platform. It also follows that a platform that is VERY different from those 
(such as mobile) will also require more adaptations.

That said, note I said adaptations. Using two completely different codebases 
(Widgets and QML) is not ideal, and we need to fix that. Moreover, the QML 
language itself needs possibly some modifications too to support those "minor 
adaptations" without having to copy files around. It's an unsolved issue.

So I repeat again the call for help: if you're interested in seeing this 
happen sooner rather than later, help out. Especially if you're interested in 
the desktop more than mobile.
