How does Stripe Tax work? Maybe it could be implemented as an ITaxProvider, though that wouldn't have any effect on #630 in either direction.

In OCC, tax is calculated separately from the payment processor, so if this service only works for checkout via Stripe then it's not a good fit. A quick glance through the Stripe Tax home page suggests, that you must manage your products inside the Stripe dashboard for this to work. Which could lead to double work for product management.
