The patches to remove Qt4WebKit support you may have seen in Fedora dist-git 
are actually not used in Fedora (at this time), but in RHEL. RHEL has never 
included QtWebKit, they have always been patching it out.

That said, Fedora kicked out the old unmaintained WebKitGTK+ branches now, 
so I think there will be pressure to kick out Qt4WebKit soon too, unless 
somebody backports the QtWebKit community revival to Qt 4 (and I wouldn't 
count on that).

But at this time, removing Qt4WebKit, or even just removing Qt4WebKit 
support from kdelibs, will break several more applications in distributions 
than just the ones that were listed in the mail. In current Fedora Rawhide, 
all these packages depend on kdelibs-webkit:
