Spigot Changes:
60c9969b Rebuild patches
The Enchantment damage increase API added previously used the
EntityCategory enum as a parameter. These values are now however
determined by tags instead of the categories themselves.
Deprecated the outdated api method, create a new overload that takes
EntityType instead and implement deprecated method by guessing an entity
type from the builtin registry based on the category passed.
This method allows
a) the tags to still be modified and the legacy
method still respecting such.
b) potential cursed implementations of enchantments of plugins to not
break that override the getDamageBonus method on Enchantment.

Cost is a property of individual enchantments, and is used by vanilla in combination with environmental aspects like tool enchantability and bookshelf count to determine the final cost of an enchantment as shown in an enchanting table.
Having access to the base cost of an enchantment using these vanilla methods can allow plugin developers to determine the "value" of an enchantment, and use it in custom logic where needed. I came across this recently when trying to assign an economic value to enchantments during tool repairing, and noticed these values don't seem to be obtainable under the current API.
