I wouldn't characterize it as such. I think it's really more of a question of normalizing the variation in favor of the most iconic versions. I think this is a reaction to how badly some 4e changes to monster lore and niche went over with some D&D fans when they actually did a significant rework of the cosmology. The D&D Next project started with a big push to figure out what it was that D&D players actually wanted in D&D, what were core elements of the D&D game experience, and I think all of this monster lore test ballooning is an extension of that part of the Next design. If it is redoing the cosmology, it really only is so with respect to the 4e cosmology since it's definitely a more back toward the basics approach. It's more akin to Dylan going back to acoustic sets rather than Dylan going electric or Billy Bragg going back to a one-man show after a few tours with the Red Stars or They Might Be Giants settling back in as a two-piece after touring as a bigger band.
Meaning after 4e they want a do-over on the cosmology but they don't want to completely alienate the 4e crowd like they did those of us who actually liked the pre-4e cosmology. Got it. That explains the polls.
