One thing that became apparent to me after evaluating amount of complexity/work/team needed to maintain React projects compared even to Vue (but the difference is even more striking with more backend backed projects) is that - it is very often way cheaper to not to use React.
What size of project and what pain points made it "expensive" in your opinion?
Because, admittedly I only have a view of react of having used it to enhance a server rendered (PHP/twig) page with rich interactions (Making a UI widget/gizmo that lets the user manipulate the data easily before form submission etc).
On the one "full app" that's an offline React PWA, our only real pain point has been the report section, because the report structure is dynamic (controlled by a config from the server) and recursive which made ensuring the correct components are shown and having performant state management challenging.
