Minecraft terrain generation produces invalid states, such as empty spaces within water, where once you interact with it the boundary collapses into a valid state. I don't think Mojang planned to have those invalid states.
Minecraft has (had?*) a lot of bugs but I don't really see how that's relevant.
*I haven't played it for many years so I have no idea what things are like these days.
