This made me lol and maybe I misunderstood but, what?
Only once in my career I've come in on a fairly mature project that was, for the most part, done The Rails Way (TM). The code did its boring job quite well and every new place I looked I was able to understand and find things very quickly.
On the flipside, people can definitely lean too much into a framework in cases where it doesn't work and leave a mess, so it it's definitely a fine balance of knowing when to break from convention.
But I have a hard time sympathizing with people who use a framework and break a bunch of its conventions for no other reason because they think they know better (ie, without even trying to make it work). Even if they are among the rare breed who write good documentation, a lot of frameworks out there have really good documentation I've already read. We're just making web apps here, people.
