Water Bucket Enchantment

I think a cool enchantment sort of easter egg kind of idea would be to be able to enchant a bucket with "infinity" with an anvil, and make it be able to pour infinite water (or lava). But the catch is, you will never be able to empty the bucket for anything else. It would bring a small interesting dynamic of whether you want infinite lava on you at all times, or be able to switch around what you're carrying with an unenchanted bucket.
