Hi Balazs,

This is something we don't want at this time.  Dealing with V8 in WebCore is pretty big maintenance burden and one I would rather not have in WebKit2 unless there is considerable demand for it.  

In your patch (attached to https://bugs.webkit.org/show_bug.cgi?id=84457), there are many intrusive changes to core WebKit2 code, making it harder to comprehend and refactor. 
Also, since a much bigger proportion of developers who develop WebKit2 don't ever compile V8, it seems more likely that the code will stop working.
