IMO you don't really need to be honorable to decide you're not surprise attacking someone. Besides, sometimes you can be a pretty cocky person that would rather take them head on (RPly speaking) amongst several other kinds of reasons characters could have. I don't think toggling back-attacks needs getting tied to a trait or some kind of intense IC reasoning, though, specially when they tend to be detrimental for the player more often than not at higher levels.

So, having a toggle for them would be very quality of life, yes! Could put it in the Preferences menu.
