Currently forgeability requires heat to exist.
This makes a heat cap be required on an item to forge it even if you don't need the heat for the item you must put it on there. These are two separate systems that just happen to be used together and they should be treated as such. There isn't any reason for an anvil recipe to require heat, it was only made this way as that's hows its used within TFC.

This makes anvils operate less like a crafting table and more like a only for this mod block.

Splitting them opens up the anvil to easier customization for pack makers and possibly more use within TFC itself.
Either a new registry option can be added or the input of the recipes can be looked at and automatically be registered.
