It would be cool if the scavenging loot modifiers were updated to use entity type tags instead of a strict entity type to make them more easily expandable. Example:
The farmersdelight:scavenging_feather loot modifier could use a farmersdelight:scavenging/feather or farmersdelight:scavenging_feather or farmersdelight:drops_feather or farmersdelight:scavenging/drops_feather entity type tag, just something along those lines, instead of checking minecraft:chicken so other mods can just add things to those entity tags. Same could be applied to the other scavenging loot modifiers, especially like leather and string, but all of them would be useful.
