Possible revisit of past mob suggestions

I know you guys have previously said that there would not be mobs like sharks,alligators etc into the game because hostile mobs have to be non realistic, except they are not inherently hostile, they’re are mostly harmless in real life unless provoked (like sharks) or are territorial of their nest (alligators and others) and we kind of already have the territorial aspect with polar bears,so maybe with this in mind those past suggestions are worth looking back at
