We know that argyle is a pattern that consists of symmetrical rhombuses. Traditionally speaking, argyle pattern has some sort of diagonal dotted lines forming X. For instance, I consider post #5854597 to have rhombus background, while I can consider post #5492244 to have argyle one due to extra outlines (dotted or not).
Despite the difference that I noticed, should we alias argyle background and rhombus background into a single tag?
Personally I wanted argyle background to be aliased into rhombus background, because not all patterned backgrounds that consist of rhombuses look like the archetypical argyle.
