Just to state my opinion (and yes, I know which bodily orifice that opinions are compared to)..........
Flying in the MA, and expecting a 1v1 is almost fantasy. It almost never happens. Someone will usually jump right in, regardless of a request not to, and usually without saying a damn thing. It could be my own fault for not being faster a killing, but I like to set up a nice shot before I pull the trigger so as to not waste ammo, but that's me
Yes, it would be nice, but again, I don't expect it. I find that if I expect all of the "taboo" behavior, I am more pleasantly surprised when it DOESN'T happen, as opposed to getting pissed if it does.
Just as an example: It has been quite a while since I have been "picked" by surprise, because I am always looking around, and if there is another plane who is in a position to pick me while I am engaged, I will not fixate on the target in front of me.
