Is your feature request related to a problem?
When using a PersistentDataContainer to hold Booleans, you can basically treat the key existing as the boolean value. So, I figured why not add a way to make a valueless tag so I can just store a NamespacedKey on a PDC and check if it exists.
Describe the solution you'd like.
A new function could be added to PersistentDataContainer
void tag(NamespacedKey key)
All it'd do is run set(key, PersistentDataType.BOOLEAN, false) or something.
Then, you can use PersistentDataContainerView#has and PersistentDataContainer#remove like you would now.
Describe alternatives you've considered.
Alternatively, multiple functions could be added so that tags don't interfere with any other data stored on the entity. Adding a list of strings to the NBT data would do this fine.
Three functions would be added to the API (I'm a little unsure of the internal PDC workings, sorry)
Inside PersistentDataContainerView:
boolean hasTag(NamespacedKey key)
Inside PersistentDataContainer:
void tag(NamespacedKey key)void untag(NamespacedKey key)
Alternatively, it could be addTag and removeTag.
These could be stored in a list attached to the NBT data, or it could assign a value of 0 internally.
