It may seem logical but it's not going to be logical to a lot of NI citizens. Half of NI identify themselves as British. Just because there was a majority to stay in the EU does not mean those people would prefer to not have a border with a country they don't see themselves as part of over a country they do see themselves as part of.
in fairness its already public - we all know that was offered and we all know the reasons it didnt work - and the thought of the DUP responding to public preassure is again a non starter - they just dont care
That's the thing though, the EU should communicate publicly about the two available options because it becomes obvious that DUP and the UK are aiming for a hard border but don't want to take the responsibility. At the moment we are blurring the topic by talking about red lines. We should put the answers on the table and let DUP and May take their responsibility in front of everyone.
