Ugh, I really really hope they don't end up sticking to their initial draft for reactions.
There is nothing strategic about toggling them on/off and hoping the enemies end up taking the actions you were hoping. If the AI decides to do something else then at best you didn't use up any of your limited resources and at worst you end up dying because you outright aren't able to perform the reaction that'd save you.
Just ask the player what they want to do instead of having them pre-emptively toggle them on or off. It works in tabletop and it works in Solasta which, like BG3, also is a video game adaptation of 5E. There's no reason why it wouldn't also work in BG3.
