Lets not forget that Disney Animation Television is run very differently compared to the regulations that Micheal Eisner had back in the day. Back then it was 52 episodes and that was it, didn't matter if you were popular or not. Only reason why shows like Star Wars Rebels, Gravity Falls, Star vs the Forces of Evil and Phineas and Ferb stayed on was cause they are popular, and some even win accolades (And now like seen in Falls, the creator can have the decision). And some were just unlucky cause of studio changes to match with the films (Earth's Mightiest Heroes for those god awful Marvel Avengers Assemble Shows, Spiderman can be tolerable but...)
Now that being said, the fact that Kim Possible Alumni are in charge of the show is a clear fantastic sign. When you read that synopsis and later read who is in charge, thats a perfect fit. And with Tangled as well getting a TV show, its just so exciting to see Disney go back to something since The Emperor's New School (which i found great to be honest)
