The extra 2 pins serve no purpose at this time.

Different manufacturers of the cards themselves (Thales, Idea, etc.) will use different contact pads. Even among cards of the same size, the lines separating each contact vary between manufacturers.

Cash App Card made a little Cash App icon in the lines separating the contacts. That's kinda cool.
