It would be interesting to hear from some european crew on this. They must have the odd occasion where someone does board the wrong a/c, if not then it is the UK that should be looking at why europe has a zero incidence rate.
If they do have the odd occasion it would be interesting to know what they do about it and how long it takes.
I would be horrified if the pax was just allowed to disembark and the flight were to carry on as normal, so the flight must incur a delay of some sort. Which justifies our system that prevents any delay no matter how short. We all know what folk think of a delay that could have been avoided.
