Plastic isn’t necessarily perfect, it can e.g. be affected by substances like acids. I’d be incredibly surprised if there wasn’t a material difference between a “virgin” piss bottle and a 10-year one.
If those material differences cause a layer of piss to stick to the plastic which isn’t easily cleanable and dissolves into food over time, they’re gonna care about them.

I don’t think someone eating food from a piss jug cares about material differences in the plastic.
