I would rather we seriously look at a way to unfork the URL parsing  
code, before discussing mechanics of how to keep it forked. We don't  
normally put ifdef paths in core code in WebKit that the WebKit  
project is not expected to maintain, so that certainly wouldn't be my  
first choice. And I do believe it will waste people's time to have the  
fork there even if there is a prominent notice that Google is expected  
to do all the work to keep it working.
