Pair Animals and Pets with Lodestone, letting them roam nearby

Bdoublo100 and other minecrafters have run into the issue that there is no in-between resting state for pets and animals -- you can either let them roam completely free, potentially running away or getting hurt, or they can sit forever / be tied up with a lead. This suggests an alternative.

I suggest that if you have a mod following on a lead, you should be able to right click the lead onto a lodestone (the way you would if you were attaching the lead to a fence post), and that will "pair" the animal with the lodestone, allowing the animal to roam but only within a small radius of the lodestone (maybe 1 chunk).
