There are a number of cases where changing from using a specific item ID to a tag would automatically add compatibility with several new mods.

For example, if Arcane Gold was to use the forge:ingots/arcane_gold tag, the material would be compatible with the Arcane Gold from both Eidolon and Forbidden and Arcanus.

Similarly, forge:ingots/pewter, forge:ingots/brass, and forge:gems/moonstone all have tags included in their respective mods.

This has been fixed for a while, just forgot to close the issue.
