Unlike always, I'd be direct: Should we merge lewis-structures and the newly renamed structural-formula because Lewis structures are clearly structural formulas and the Wikipedia page for "structural formulas" says I'm right in saying that and no matter how much high schools love Lewis structures and how many questions we get from them and how much unpopular Newman or Fischer projections or others are at least in elementary courses of organic chemistry they're still a clear subset of structural-formulas and keeping the tag would make no sense because someone who wants to tag their question as lewis-structures could tag it as structural-formula legitimately and if we merge them they could get to tag their question as structural-formula even ignoring the fact that Lewis structures are structural formulas by simply typing "Lewis" in the tag box?
(i.e. Should we merge lewis-structures into structural-formula?)
