2020 Irish Open Moves North To Skirt Quarantine Rules And Attract Better Field?

I am happy that the 2020 Irish Open is going to be played.  Don't get me wrong. 

It was meant to be in Mount Juliet in Kilkenny and has now moved 215 miles to Galgorm Castle in Northern Ireland. The reason? Prospective players returning from the US Open to play in the event will not have to quarantine for 14 days in Northern Ireland, whereas they would have had to if played in Southern Ireland.

The US Open finishes on the Sunday before the Irish Open from 24-27 September. My question is how many of the 40 or so European Tour players in the field will actually want to travel from New York to the Irish Open?  I understand there will be the Irish players that will, Shane Lowry and GMac most assuredly, but it's hard to wrap your head around moving an entire event to a) take advantage of restrictions and b) to accommodate what might just turn out to be a handful of players? 

I'm thoroughly confused about this.  Coronavirus versus golf.  No joined up rules on restrictions between Northern and Southern Ireland.  But by the same token The European Tour have to be commended for getting a tournament organised in the current Covid climate.
