I'm Really happy about this development, now we have the precedent that if Brexit is unbearably stupid for an area, it can stay in. That certainly counts for London and Scotland at least. Even after "Brexit" has supposedly happened, Various regions can keep fighting for whatever deal northern Ireland has.
I'm tempted to tell Northern Ireland that Brexit means Brexit and they can live with a hard border. Tough luck, we all voted to chop our nose off, let's get cutting and place all the blame at the tory's feet.
