I think since those scenes were already filmed, it would be more of a waste to just store them in FoX's cloud library. At least, with the deleted scenes, we could at least know for sure if the original 3rd act is better or worse. However there are so many scenes filmed for Dofp, X2 and First Class that weren't included for the home media release. The Gambit/Marrow/Beast scene in X2 during Cerebro's mutant attack (mentioned in X2's dvd commentary). Storm and company interaction with Bishop when they arrived in the X-temple (seen in a bts clip). Havok in costume blasting outside of the X-mansion (seen in the trailer). The deleted scenes shown in Fant4stic's first trailer weren't even released for home media as well.
