They've shown they lack the foresight to imagine that more than 5% of players would want a house, that mudra lag would be a problem if someone didn't live right near where the servers were located, that inventory just might become a problem with the continuous addition of new classes, etc. As for evidence, no one but SE can provide that, but we can compare it to preexisting systems.
2.X on is built on 1.0's server infrastructure, which was probably the worst of any MMO period. It was so bad that the entire server could hitch from someone changing zones. It definitely limits what they can do, and tbh I'm amazed they've gotten it to work as well as it does.
