keep baby animals babies using name tag

It would be really cool if just like we have "jeb_" and "dinnerbone" we could add a name tag with a specific thing to keep baby animals babies. Now that the new look for baby animals are coming It's the perfect time to add such a feature. Because as we all know players have thought baby animals to be so cute for years upon years now. and Especially now more than ever. adding something so simple as a specific name tag to keep them babies would be an easy add while also helping players that just love their cute baby animals too much to want them to grow up. it could also help with people who want to add that extra detail into a world. getting to keep some animals babies could be a great addition to that.
