So I don't think this is a real problem in practice.
Grafts are already unreliable. You cannot sanely merge over a graft,
and it has nothing to do with generation numbers.
I'm actually sorry that we ever did grafting. It's fundamentally
broken, and can actually destroy your repository (by hiding real
parents and then causing the commits to get garbage collected). So I
don't think grafting should be used as an argument for or against
anything - it's a hack that breaks some fundamental git database
constraints.
