I will give a counter point.
I
love well-designed opinionated frameworks. Whenever I want to do something simple, I agree that a framework may be overkill. A micro-framework is nice for those scenarios though.
However, whenever I build a project that will be maintained or extended by many people, opinionated frameworks give me the advantage that they force you to do things in a particular way.
Django is a perfect example. If all I am doing is two or four pages that just return static HTML, then why would I pick that at all? A new django project creates a specific file structure: urls.py, models.py, settings.py, views.py, middleware.py, etc. If I get a new Django developer that is not familiar with the project, I can pretty much drop him in and he will not what is going on quickly. I don't need to explain what a viewset is because chances are that the dev has used Djano Rest Framework before. Whatever changes are made, will follow the same patterns, so maintainability overhead is reduced.
When you add a project that is built from scratch without using a framework that has strong stances on how files should be organized, all bets are off. You have to spend a lot of time trying to wrap your head around the custom abstractions that have been built - and it is hard to argue that some of that will translate to a different job.
Yes, of course when you want to do something else that forces the opinionated framework to do things that it was not designed to do, it is a true pain - but you have to ask yourself if for that particular case it makes sense to use that framework at all (most likely not).
Frameworks also evolve. I use to curse constantly when I had to touch a Backbone JS project in the past, but now, I can jump and look at a React project that uses Redux and get to make changes right away without paying high cognitive cost. It may not be perfect, but it gives me structure and pre-defined patterns to worry about solving the actual problem I want to attack - and not waste time trying to create yet another leaky abstraction. My two cents.
