Long story short: Implementing autocast for spells is way more important than making new civilizations and whatever funky stuff is planed in Shadow.
Nah, I disagree.
The game is single player. If the power of your OCD compels you so far that you must absolutely have every single one of your workers optimized by following them around with an adept then so be it. Just because you can do something, doesn't mean that you have to.
Much of this mod is roleplay, we're all sitting around imagining that we're the king/dictator/grang poobah of the elves or dwarves etc. I happen to like the fact that it costs something to use magic, UI 'optimizations' that inevitably feel like shortcuts only serve to pull the player out of the scenario.
