One thing I don't understand about Varnish for M2 is how it will work with prices. Especially since M2 is meant for B2B, there could be customer groups with different prices. So when user 1 (customer group A) visits the page he will get $10 for product A but user 2 (customer group B) will get $20 for product A.
Is the price block automatically hole punched with Varnish for M2?
