Framework fatigue is understandable. Need? No. Want? Yes and maybe. Fortunately, no one's forced to use any one thing. That's because of the answer to your question: yes, no, and maybe.

One might want to fear a day when the generality of a no displaces the spirit of a yes, about whether an activity is justified inherently.
