I ask cause there are a few projects that i am aware of that seem to be staying with GTK2 and no plans to move onto GTK3. Is this something that will affect them in future? The main project in mind is Ardour. My understanding is that the main developer doesn't see the point in moving to GTK3 cause there aren't enough benefits. Is he right and if they stick with GTK2, are there problems down the road they might encounter in time?
I know XFCE have some plans about moving to GTK3 at some stage but what about LXDE? Would it hold the project back to stick with GTK2? Any thoughts? Or any other examples of projects that don't seem to have plans to move onto GTK3? Also, did similar happen with the move from GTK1 to GTK2?
