Holding people has been a thing as far as I know, in wars and when people chain break, etc. Elimination is far from the only circumstance in which it has been used. In wars no one seemed to have a problem with it. Eventually the person has to chose and outcome, or they time out and it counts as a defend for you. It can be annoying, yes, but it's a tactic that's been used for ages, both to restrain people and to have hits ready for bonuses, for example.
