The base point is there's no need to reinvent the wheel, especially if what you are seeking is an object to help something be more easily moved.
Video games on the whole are focused on creating systems to enable players to engage with the game. Thus, it's possible that a system might have already been explored that does something similar to what you're looking for. Thus bringing up systems from other games can be relevant.
At the end of the day, it will come down to the developers to decide what exactly is used. What systems they want and how they go about it (For example, BG3 is TB but some people could have wanted RTwP or full RT). This often means that it requires outright disregarding some players feedback/wishes and stating "This is what the game is" because again, different people have different opinions. Some people would like RTwP, some would like TB, some would like both options (Some games let you swap between both modes. PoE2 created a TB mode after being originally RTwP)
Larian mentioned EA as a form of back and forth with their community. They clearly had some direction in mind for the turn based combat, tried to make it feel fluid and quick. For example, besides Swarm AI and simultaneous turns, they also drastically quickened the pre-cast animations for spellcasting when compared to their previous titles. We are not only talking hypothetical here, maybe I phrased the question poorly so that it might suggest it. I think the idea to straight up borrow reaction system from the other title should have been disregarded in favor of something organic with no pause. Presets for conditional triggers, maybe? An even quicker paced combat could have revolutionized the turn base genre and pulled in some fans of the RTwP or full RT. Instead we ended where we started, with the pacing slowed down.
In any case, reactions we have now are way better than toggles we had before! It was a safe bet for Larian. I just wish we were more idea-driven with our feedback, rather than focused on other games and their ways, sometimes.
