A sidenote here in light of my recent Ableton talk:
I love electronic music, and I still listen to dubstep on occasion. And yes, I've done work for clients that include drop-like sections. I'm not against any certain usage of form, and I'm not putting a stake in the ground saying using drops or instrumental breaks are evil practices. This was simply an observation of where we're headed collectively as producers. I'm just a music nerd who loves to observe things, and have been studying this shift. I hope that it's a conversation starter!
