I think plenty of people would like that, and I personally think that's a better path forward than dwelling too much in the past and trying to bring back Vanilla servers. I would prefer they take this feedback on board, learn why people liked Vanilla servers, and use that knowledge to improve the game going forward, and try to bring back some of that old spark.
Y'know maybe "pristine" idea isn't THAT bad, if they made some additional improvements as well. I wouldn't be totally opposed to them creating a kind of "hardcore" realm with the rules they mentioned for pristines and some additional things, like much more dangerous mobs, named quest mobs being stronger elites and multiple difficulties removed from dungeons/raids to be replaced with the hardest version only :P
