Growth Clock that prevents baby mobs from aging

For the new update, where many baby mobs get new textures, many players want a way to stop them from aging. It would be a great addition to implement a "Growth Clock," crafted with Echo Shards like the Recovery Compass, which you can right-click on baby mobs to stunt their growth. Once you right-click a mob to prevent it from growing, there would be sculk particles sourounding that mob if you are holding the clock, so you know which mobs are marked and which are not. If you want to remove this effect and let them grow again, you can right-click the marked mob with the clock again.

This would be a great feature, not only because it would give players a tool we want, but also because it would give a new use to an overlooked item: Echo Shards.
