It's difficult to see a way to expose the QNetworkAccessManager in the public API the same way that it is with WebKit1.

There is something that does something similar which is called an InjectedBundle. A .so file whichs path is given to the WebProcess that will be loaded and accessed through a set of internal APIs. It is passed through WebContext::create, which we currently fill with an empty string in QtWebContext::defaultContext. The main purpose of this mechanism is testing.
We can't guarantee binary compatibility for bundles, so there is no plan to expose setting a custom bundle path through the public API. However if you would like to maintain a minimal set of patches on top of QtWebKit to add advanced WebProcess functionalities, I think that this would be one of the less painful way regarding maintainance. The internal API of bundles will change, but should be somewhat stable between releases.
The best way forward is still to agree on common functionalities that we could add to the public API, so please use at your own risks.
