Here's some violent agreement... I think this is a great product - if I am building a site, I want to concentrate on building features for that without first building technical bleeding-edge interaction from the ground up. Sooner or later I may want to do something with this that isn't possible in the proprietary system, yes (although that's not guaranteed at the starting point). If I get to that point with traction and money to invest, I probably would do exactly what you suggest, i.e. build a bespoke solution. And, in that case, since the Firebase system acts as a modular component, refactoring this solution might even be a better option than refactoring a messy roll-your-own solution.
