I maintain that talking about integrator in that basic configuration is too simplistic a point of view. You need to be more specific on the application.
Talking about integrator as just a LPF inverted op-amp with a cap as feedback is like talking about a RF power amp as just a transistor in common emitter or common source configuration. You miss the moon talking about it like this. People can write a whole book on JUST this common emitter stage when you get into the RF world. It is all about the matching, filtering, efficiency and other calculation and design. Yes the simple little few formulas of basic transistor is still the main equation, but there is just so much more to this little common emitter stage than just the mathematical equation. It is not just a common emitter stage.
Lastly, this is my opinion and it's not up to you to say whether it is correct or not. Many people here are studying to be an engineer. It is important to know not to just look at everything just from the textbook. A lot of people can get good grades but never transition into a good engineer because they cannot transition from the textbook theory into real world. That's the reason it is more important to talk about application, looking at things in a more macro point of view. I spent 30 years designing these kind of circuits and looking at an integrator as just the circuit you show is woefully inadequate.
