I am on Wikitree regularly and do try to spend some time reading in G2G, but did not catch this. I just recently used FAG as an abbreviation for Find a Grave in some research notes... and would certainly not have if I had been aware. 
Perhaps when something this important for the whole community is decided it should go out in the weekly newsletter that arrives in my email box under "Important Notifications" or some such header. The posts on G2G are almost impossible to keep up with, they drop down quickly and unless I am on G2G every day, all day, I will not catch them all.
Just my 2cents for what its worth, from now on it will be FG.
