One part of the story that's probably relevant is that RoR makes getting started with relational databases easy. That can be extremely intimidating otherwise; I meet a lot of juniors who have never touched them and don't know where to start. Because it does cover the full stack, in a way that devs in a conventional enterprise wouldn't ordinarily do, and gives you pretty good hand-holding while you do it, it takes a lot of the fear out of parts that might otherwise look intimidatingly complex.
