Yes you have posted them before and I have looked at them then and again now, but I don't see any details in any of those links. First I head of that comment by Macron. But I was not aware that he was a EU spokeman, with the sole authority to make specific demands on behalf of the EU, plus it is a load of crap and does not help the situation.

You have to be aware, that the Irish Authorities have to be vague/deny they have any plans in place, because if they start publishing specifics as to how it might work; it runs the risk of becoming a self fulfilling prophecy as brexiters will start saying they can live with those plans.
