I couldn’t think of one single scenario where this might be remotely handy.
I literally gave you one - HDR toggling. You disregarded it because you didn't want there to be any reasons.
Here's another - you could ask copilot to check your emails for an invite to a party that you are expecting, add the party to your calendar, create an item on your to-do list to get a present, and forward the invite to your partner.
How's that? Is that not something that could be useful?
