There's something I never see mentioned in this discussion: you can be flexible with what libraries/frameworks you pick, but you can also be flexible with what you build with those. If doing things exactly the way you envision involves building the world from scratch, it's often better business to go with a "less elegant" solution that can be rapidly pieced together from mainly ready-made components. I've often earned long-lasting trust and cooperation of clients by asking whether they would like to adjust (or forego entirely) that one feature, if the project ended up being 20 or more % cheaper/faster to deliver. And given that choice, it's surprising how flexible businesses can be.
