Should corkboard imply cork?

corkboard = cork

I realise that the “cork” tag is probably supposed to mean the object, but it’s also being used for the material. “Corkboard” is only a small tag, but I think it’s a worthwhile distinction and not being used to its potential. “Cork (object)” and “cork (material)” could be split, with the former implying the latter, but that may be going too far.

I don’t think we should - people won’t be looking for corkboards when searching for corks.
