By edorian:

After back-porting it and testing it again I found some issues with the SF2 test suite that makes ~15 tests fail. They call ->getMockForAbstractClass with ($classname, array()); and it fatals.

Not sure why that didn't show up on my initial tests. I'll investigate

Given those issues maybe its not good to do release that change.( At least not before 3.7 comes around.)
