Confirming in 24w46a. However; please refer to the pinned comment for the most recent context on this issue.

The use_cooldown component does work for some item interactions on entities, however; some other items do not work like shearing a sheep, naming an entity, putting an item in an item frame, leading an entity, and more.

Steps to Reproduce:

1. Spawn two pigs
2. Get the following item stacks:

   /give @p minecraft:name_tag[minecraft:use_cooldown={seconds:3},minecraft:custom_name="pig"] 64
   /give @p carrot[minecraft:use_cooldown={seconds:3}] 64
   

3. Use both items on the pigs

Expected Result:

Both items would go on cooldown once used, because they are both item usages on an entity.

Observed Behavior:

Only the carrot will go on cooldown, and the lead will not.

Notes:

The carrot working is likely because the item also has an eating usage as well.
