It probably is if you have to deal with > 25k LOC code base like what Angular has.

Ok, for the down voters. Angular is HUGE. And all that code has to get shoved onto the client side when someone visits a page. And that's JUST for the framework. We aren't even talking about the application code yet. More and more clients are mobile. Nobody sees a problem here? You're using more (precious) data, it's slower to load and slower to run. It's just a nasty little trend going on.
NOW LET'S SEE SOME FREAKING DOWN VOTING!!!
