Maybe it could be considered to progress the 'timeline' of Phineas and Ferb. Instead of viewing their days over the course of one summer, we could view multiple summers - possibly one each season - until they're fifteen years of age. That presents two choices: begin a series focused solely on their teenage lives, hence leading up to a Seer trilogy, or kick things off with the movie(s) and transition into the newer series.

Of course, that's not likely to occur, but it's fun to hope! It would be a neat way to advance P&F without necessarily outliving its stay.
