I don't personally use Ruby on Rails, but there's a strong benefit from a framework or system that has been pressure tested in the real world with a lot of eyes on it - especially open-source ones that are the result of the accumulated judgement of many users.

Many solutions that seem obvious are less than so after a bit of prodding - but without that sort of discussion or pressure both humans and agents will often land on the thing that works first.

Where it tends to really matter these days are on the opinionated decisions... i.e. the trade-offs, things that can't be clearly validated etc.

So in the end I think we'll find that these sorts of frameworks etc. will continue to be, and possibly become more important - when your use case matches the intent and goals of the tool. This opinion differentiator is likely also the thing that combats the current issue of proliferation of quickly-built tools that more or less do the same thing.
