I'd just like to point out that 10 units of fluid = 1 litre so that 50 unit 'barrel' is more like a 5 gallon tin of paint than a 50-gallon barrel. That said, an 8000 unit 'barrel' would probably be kind of silly without also adjusting tanks and such.
Yeah, just a bit, but it does go hand in hand nicely with deadlock crates and a robot heavy base that needs to move a lot of fluid around to those big 200k tanks. It scratches a very specific itch!
