Yep, the hazards of broken glass are one of the downsides of glass. However, we have that situation now mostly with beer bottles. I routinely pick up roadside trash in my subdivision and much of what I pick up is glass beer bottles. The other downside (as others have already pointed out) is the weight of heavy glass containers built for reuse. It raises the cost of distribution.
