Since Fabric and NeoForge have unify their tags, it would be a good idea to mention these in Smithed documents so datapackers can utilize these tags to get bonus mod compat out of the box with their datapacks. Perhaps a link to the modloader's data folders? Since over time, new tags could be added.
