I think some of the bigger/f-t clubs are in favour of switching to a summer season, while also preserving Boxing Day, as you say. And at least part of their reasoning is to help them in Europe.
But I'm not sure the smaller clubs are so keen (if nothing else, unlikely to qualify for Europe themselves), while I'm pretty sure the IFA is opposed, since they've put a lot of work into creating a pyramid, so they won't want the two senior divisions cut-off from the Intermediate and Junior (winter) leagues beneath them.
Sound familiar?
Personally I'm opposed, but then again, I've long been a hoary old traditionalist. Though I would also point out that the IL's results in Europe have been pretty good for the last couple of seasons. Tbh, a summer season might help, but there's a whole lot more to competing in Europe than that i.e. greater all-round "professionalism" (both literally and figuratively).
Meanwhile, the introduction of the Europa Conference League may actually do more to help the IL clubs, since they should be able to compete better with that standard of club, most of whom also operate a winter league.
