Sometimes it is best to go for it. I remember reading an interview of the Paypal co-founder in which he said that when his site was launched he saw a lot of demand from eBay users but since they thought their site was not ready(?) for that, the fought tooth and nail to keep them away. But then something changed and they started allowing eBay users to use their service and the rest is history.
It could be a similar turning point from Stripe as well. Every time this comes up a good portion of the thread is dedicated to them not being International. Maybe if they just started doing this on a trial basis they will see how much business they have untapped. Or maybe some other business can use this leverage to offer similar services to instantly enter the market.
This is not a case of "the experience isn't quite right". Finance is a heavily regulated area and failure to dot your i's and cross your t's could mean jail time or fines consisting of very large sums of money. Furthermore, failure to understand how to protect against fraud in each region is a costly mistake (one PayPal spent $300M learning).
Sometime "launch it and hope for the best" is not the right answer (though it very often is).
