Actually, it is functioning as a "members club." Membership there is full, the waiting list long and play severely limited, even to other Union League members. Effectively, the same people are playing it regularly.
I played it last fall and was enthralled by the scale and scope of the redesign. Its features are bold and unusual. There are a number of world-class holes across the 27 and most, if not all the rest are a mix of fun and test. There are plenty of quirks and areas that produce visual excitement, but near artificial penalty It may well be a golf unicorn having seen the extinction of one modern course and the construction a 1000% different one in its place.
Union League National (Cape May) won't be loved by all. The architecture is so often unique (although there are plenty of strategically solid holes) that it will produce polarizing opinions. IMO, there is more than enough room in the game for something so different and interesting that I can't wait to get back and play it a few more times.
