Because in my experience the "out-of-the-box" solutions always break down the more you want to customise them. Now I rather prefer solutions that have customisation in mind from start, so it's always easy to switch things.
I remember when that wave hit the Ruby/Python space, with things like Pyramid/Pylons. These days that seems to have gone the way of the dodo, with the big monoliths still being around and then some minimal HTTP decorators like Sinatra/Flask/Node. Problem is that the middle ground would require a level of modularity that we still haven't reached, despite all the talk of "software ICs" that came around with early OOP.…
IF you think it went the way of the dodo, I'd suggest doing a bit of better research before predicting the future :D Because IMO you are seriously off here.
