Something like that. They do certainly still handle burials and all of that.
In my own personal headcanon, I'd assume well-trained members whether before or after the Calamity would have been trained in the older arts, but the public-facing ones are the elemental stuff. Don't forget that there was a ceremonial jeweled dagger used for spellcasting once! (Instead of say, a wand or scepter). The method of channeling aether hasn't changed, just, like how Warren said, what it's being channeled to.
