If 0 is entered as the seed in the world generation screen, Minecraft will choose a random seed instead.

I wouldn't call this a bug. I think it's intentional. What does minecraft have to work with if you give it nothing? Zero probably breaks the algorithm that's used to generate the world. I know nothing of algoritims or anything but.. Zero multiplied by anything is zero.
It is certainly possible that the algorithm doesn't work with 0, but as a computer scientist, I can almost certainly say that if it works with any other 19 digit numbers, it should also work with 0. I've also tried this with -0, and 0000000000000000000, and the behaviour does not change.
In multiplayer games the seed is hidden (and displayed as zero) so that you can't recreate a server world offline, and then loot the online world for stuff you found in the offline version. Given this, forbidding an actual seed of zero makes some sense, even though using seed 0 in an single player game would be harmless.
Yes that would make sense.
There's also been some confusion in MCPE, which does accept 0, which is treated the same as -0, and 0.1, and in fact any string starting with 0... but there probably would have been just as much confusion if 0 acted like a non-seed.
I don't see any particular reason to expect 0 to act one way or the other in this situation, so I'm marking this "Works As Intended" until I hear otherwise.
I believe the reason here is that the game treats 0 as no seed given.
This causes it to randomly roll a seed based on your current system time.
So AFAIK, this is intended.
I think this is a bug, creating a world and then changing the seed to 0 with an NBT editor works just fine.
This is a bug, there is a difference between a valid seed (which is any signed 64 bit number including 0) and a 'null' seed which should make it generate based on system time.

If you want to get the seed 0, type "creashaks organzine". I also found a pink sheep on this seed.
Does 22w03a allow this to happen?
Can confirm
