Totally disagree.
This suggestion mostly mean "use Solasta's reaction system" or "use the current bad BG3 toggle system".
Yeah, that's just because you seem somewhat unable to accept that you can't have your cake and eat it too.
You either get a reaction system that does reactions properly and attempts to stay faithful to the D&D rule system OR you have to come up with some (probably stupid and ineffective) new made-up mechanic to replace it entirely, like automation or abilities that work completely differently.
This imaginary promised land that you are chasing where you can save face claiming to stay "true to D&D" AND not have some form of confirmation for reactions from the player simply doesn't exist.
And both the OP and your recurring arguments against prompts are a a struggle to solve a "problem" that doesn't even exist for many, on a premise that these same "many" disagree with.
