I wanted to suggest a feature that would make rule configuration even more flexible:
Support for Minecraft/Forge entity type tags (e.g. #modid:tagname) in the mob field of rules, as it is in commands.

This would allow users to group mobs via data packs or mod-defined tags, and write cleaner, more modular rules especially when targeting many entities from a mod, or managing themed mob groups.

For example:

{
  "mob": "#forge:dogs",
  "result": "deny"
}

If this is already a feature or somehow possible, please let me know! I couldn't find anything that would make this possible in an easy way.

I will add this for next version

Ready for next version
