If it was interesting macro, or any kind of choice was involved (ex. do I spend 100 power to activate the global), then it'd be worth the macro. Meaningful macro/micro adds to the game positively, giving you more to do and more opportunities to git gud.
As is, it's just pointless busywork. 2 Shrines and you just have permanent uptime, there's no choice, nothing interesting about it, no meaningful decisions to make about when to activate it.
It's not a big deal, control groups let me keep my Shrine of Memory or Cultist Masters or whatever up if no one else is doing void manipulation, but some kinda autocast toggle, or doubling the cost but making them work like Wheel of Gifts in terms of just being something you 'turn on' after building, would be a nice QoL change.
