Even in our situation, where we are a 2-person consulting company that isn't taking any outside investment, and have to run pretty lean (since we only get to eat and have a house every month if we do enough business to cover it), it's not worth our time to switch.
But at a higher level, the Stripe Atlas (and Stripe in general) people have been SO responsive and helpful that I'm surprised they haven't sorted this out yet. It looks like they've even popped up in this thread, so I hope and suspect that will happen soon.
With the AWS credits and how generally easy it was, I would definitely recommend it to others who are looking.
