Maybe for Comcast, but I doubt it is for Disney. Disney already purchased BAMTech which handles streaming for MLB, HBO, ESPN, League Of Legends, and many others. They have been working towards using that technology for a Disney streaming service that will debut sometime in 2019. That company is already closing in on Hulu in terms of value and would make integrating Hulu's tech and employees difficult. The only real value Hulu gives Disney is contracts for content, but those contract are only temporary and good content is still the core competency of Disney. It wouldn't surprise me if Disney proposed the original deal with the expectation that they would need to sell off Hulu to a competitor in order to get the political capital for approval for the rest of the deal.
