PCI requirements are TLS 1.1 minimum. Stripe's change is of course is due to PCI certification and 1.2 is strongly encouraged, but 1.2 is not the defacto version required. They could have just disabled 1.0 and keep 1.1. Just wanted to correct the info. (Also happy that they didn't take the minimum and took the extra effort to implement 1.2)
