I agree. I'd go further: even if we were running some kind of crazy ML on a per-merchant basis, I still don't think we could cater to every single use case. I don't think that any UI we build -- no matter how many knobs and whistles it has -- will handle everything. The Checkout page points out that you can still build every pixel of the UI yourself, and Stripe will always support that. Checkout is another option alongside the integration we've always supported, not a replacement.
