Let's be clear then:

If there's a Qt Quick 1 library, I'd like to see an upfront commitment from a 
group of people to maintain it and for how many releases they plan on doing so 
before finally deprecating and removing it. (for example, deprecate in mid-2013 
[5.2], mid-2014 [5.4])

I know that predicting the future is hard and changes do happen unexpectedly. 
What I'm asking is for a certain degree of confidence, especially because we 
all know how many hacks were used in developing the QtDeclarative and how much 
of QtCore, QtGui and QtScript internals it made use of.

Speaking as the QtCore maintainer, I don't want the burden upon me to keep 
compatibility with a library that extensively (ab)used the internals of my 

If that guarantee cannot be given, I will oppose the inclusion of QtQuick1 as 
part of the Qt 5.0 release.
