Just FYI
A Qt version is supported by the rule x.y.z +1 which means that as Qt 4.7.0 was released 21 September 2010, Qt 4.6.3 will be obsolete 21 September 2011.  

No more patch releases are planned for Qt 4.6 unless a security issue would appear, and if that happens we should probably be able to fix such an issue directly in the QtWebkit 2.0 version shipped with Qt 4.6.x

In my opinion you can remove 4.6 dependencies from trunk without causing any trouble.
