wandering sniffer eggs

Hi community, Mojang. I am posting about a new idea for the sniffer egg. the wandering trader is currently not all that useful and I personally just end up defeating them. but what would make me stop and check their loot would be if they could trade the sniffer egg. it makes sense, as they can already trade small dripleaves and moss blocks, two things both found in caves, so it only makes sense that they would have discovered an egg here and there as well. it could even be extremely rare, making it something to take a screenshot of. of course, this is just an idea, but please at least consider it.
