CertainNetherMobs Have a Chance to Spawn With the Tag ImmuneToZombification

I think it would be a neat idea to have Hoglins, Piglins, and Piglin Brutes to have a small chance to have the tag 'ImmuneToZombification' applied to them. This would be given a very very small chance to happen but it could have a few potential uses. The main one I was thinking of is something of 'mob zoos' where we try to collect one of every mob in the game and the only issue with this is are the three nether mobs because we can have every mob in the overworld and end, but not those mobs. For the nether, we cannot have water there so the aquatic mobs can't be in the nether and snow golems die as well and I doubt there will ever be a way to get water in the nether. That is one of the implications of why I think it would be cool to have this tag be randomly assigned with a very low chance of happening just so mob zoos can be complete. Also, not just mob zoos can be created with this tag but various other things can come out of this that I may not be thinking of. You may say it could be busted or something as piglin bartering farms in the overworld may be developed, but this would be a late-game thing as it is a really rare chance of happening and you would need a large-scale farm to try and obtain this tag on those mobs and I doubt this would be done early-game or something.
