[Development] Future of Qt Quick 1 in Qt 5

[Frederik Gladhorn]

Hi,

I think the dust has settled quite a bit and the declarative module is 
becoming better by the day. We have seen it evolve and the new Java Script 
engine is running smoothly (and actively worked on, sadly it will have one 
known crasher in the 5.5 beta release which has been fixed in the mean time, 
so it should be good for everyone with the 5.5 RC).

One question is if there is any reason to maintain Qt Quick 1 in the future. 
It adds burden on maintenance, needs to be patched regularly to move with 
changes in qtbase etc.

Since KDE moved over the Plasma desktop to Qt Quick 2 (on which I'm writing 
this email), I feel confident that the time has come to move everyone over.
For the no opengl acceleration use case, we provide the Qt Quick 2D Renderer 
as backend. (https://blog.qt.io/blog/2015/01/22/introducing-the-qt-quick-2d-renderer/)

In short, is there any reason not to remove Qt Quick 1 from Qt 5.6?

Cheers,
Frederik
