sorry, no its not irrelevant.
you could stop Euro riders/racers coming over , likewise we could stop going to Europe to race but there would be so much 'do I need or not or only for x time', the paperwork would take longer to process than journey time. prices would go up.
bear in mind, the original case was brought by a man up a ladder being hit by a tractor, it opens up major concerns , look at whiplash claims as another example. these are being clamped down on now and that's in the UK.
