Before I start: yes I am aware that GPQ has been long gone in the game.
I was going through some maps on my website today and I realized that the all (well, almost all, except 1-2) the GPQ maps were removed from data entirely. I have no idea when this was done (@Fiel; probably has a much better idea than me), and I've never really seen Nexon remove the entire set of maps like this (LMPQ, in comparison, still has its maps in data, despite it not being used; edit: alien PQ maps are also still in data).
So does this mean that GPQ will never come back? Sad day for me then.
