Please describe the new feature or change.
There is slight possibility that present behavior is not intended, but I assume it is, so I make this issue in the format of feature request. From reading the wiki, I learned that items that have "Curio" slot type among slot types they can be equipped into can actually be equipped into any slot. I therefore assumed that if I create a slot in the Curios inventory that will have this type, according to this theme it will be able to accept any type of wearable, but it doesn't seem to be the case, and it only accepts items that specifically have "Curio" tag.

Please describe why you want this feature.
I'd offer to make it so that "Curio" slots can accept any wearable in general, as it would be a unique feature that otherwise is very difficult/not possible to make with external implementations. Of course, developers will have to use it carefully, taking into account that other mods using Curios API do exist, but in the end same goes about having wearables with Curio slot type.
