FWIW, Qt WebKit is coming back, and we may support Android as well.

I can use either "import QtWebKit 3.0" or "import QtWebEngine 1.1" (with the latter, changing my WebView to a WebEngineView too) and I can then see a webview that works with no issues, but neither of those are available on my Android target (nor, from what I understand, will they ever be).
