I would not necessarily disagree with the problem of upstreaming work. But you said that most likely you wouldn't be able to branch WebKit anymore because of the compiler requirement. At least for Qt. Do you have other interests in QtWebKit beside the integral part of Qt so that it makes sense for you to maintain the port further?
Another question that is just partly related to WebKit but more curiosity. Qt is deep integration into WebKit. We have (had?) a lot of Qt specific code in core WebCore to support QtXML and other things. Blink already stated that they would not accept such deep interventions in their platform. Is all that not important for you anymore? Can you operate with libxml2 and other libraries from now on? If that is the case, can't we limit the Qt specific code to just /platform/qt and remove all other Qt specific dependencies from WebCore?
