I read in the main changelog that only Chaos factions are able to raze settlements anymore.

Why is this? It's a pretty critical feature for groups like Dwarves when fighting Vampire Counts or Empire fighting Orks. or Orks invading Empire. It's the only way to secure territory for themselves against those factions, and in a lot of games with vanilla I find it absolutely critical to obliterate the vampires in this manner just to buy myself breathing room in the northern provinces when I play Dwarves. I can't imagine it'll be any different when I play Orks.
