No, Disney still has to deal with the district, and whomever the state decides to sit there.. and all the 'how can they make life worse for disney' points are all still the same. Nothing that happened since RCID was torn down touched anything in the comprehensive plan that was in place and the only portion of the new developer agreement that really matters is it locks in new land management minimums for the property as a whole. Disney basically promised 8 billion dollars and capitulating in return to ensure they get to define the new TBD comprehensive plan like the old days... with their interests at the forefront.
Everything else is still as it was with the new District in power... the difference now is right now you have District management that is cooperating with Disney. It's just an example of how far things can swing based on the District's board... they can be completely antagonistic, or they can be completely submissive... all within the same structure.
Disney gets to lock up the master plan for the property - but everything else is still at the whim of the Governor because he can swap people to do whatever he pleases.
