It's a fair question, and I admit I didn't outline that in the proposal. The 
maintenance of the Qt 4 port currently costs us

     (1) Separate *Qt4.cpp files in a few places (including the much loved 
JSC<>QT bindings ;)

    (2) A fair chunk of #ifdefs

    (3) A bot to maintain (This is a very high cost, especially for Ossy).


I'm proposing the remove the Qt 4 port from trunk because nobody appears to be 
interested in taking over that maintenance in trunk. Andrea on the other hand 
volunteered to do an out-of-trunk maintenance, which is a great opportunity I 
thought.
