I believe whatever makes the game enjoyable for the greatest number of people is the correct play.
The biggest example to this kind of issue has come up with Insurrection. My big, dumb battlecruiser deck has the best, spookiest board, and can kill the table if blockers are cleared with the mass mind control.
I respond by conceding. One player is salty, I’ve definitely lost (though helped play kingmaker), while two more players are still in the game- net political positive for the next game, and the current game continues with 2/3rd content.
Usually, the insurrection player is then allowed the classic take backsies and can use their turn and mana differently, essentially killing target player for nothing! Lots of ways around it without taking away the agency of concession at whatever speed you want.
That is most definitely poor form.. If that's what floats your boat then go ahead, but I wouldn't sit at the table with you again, even if it did benefit me in that particular instance.
