Would it be a good idea to use bleeding-edge mesa PPAs when building snaps?

I have a few games in the store. For my users running open source graphics drivers, would there be any advantage to me adding one of the bleeding-edge mesa PPAs as I build my snaps? Users who are on 18.04, Solus or some other reasonably modern distro are going to have newer kernel drivers. Are they being disadvantaged if I continue to bundle parts of the graphics stack from stock 16.04?
