Look who it is! Great to see you around again.
I don't have much to add when it comes to improving compatibility for EE/EET, but I can point out that the "Druids can wear metal" component may not serve much purpose when it comes to Item Revisions. IR has a separate component for adding these restrictions to druids and fighter/druids, so players could get the same effect by just not installing the IR component to begin with. However, your component may still be useful in combination with the Druid Remix component from Divine Remix or other mods that bundle the usability changes with additional features.
