I am having some problem finding out if products(read Variants) that is sold out is getting removed from consumer portal. 

For example. Merchant publish product with two variants: Green and Red. 
Both Green and Red is published with two sizes: Medium and large. 
2 Available product pr variant. Seller sell two red-medium, meaning Red Large is still available for purchase. Do we count down, and removed red medium(variants) from consumer portal?
