Crop_tops implication tank_top?

I'm unsure, should crop_top have the implication tank_top? from the wiki it mentions that it is a tank_top that is cut short and mid-waist... but isn't it still a tank_top?

Not all crop tops are tank tops as said in the wiki page. Take crop_top t-shirt for example.

A tank top is defned by being sleeveless. And a crop top can have sleeves.
