>Apps can use SMS or open the OS browser to accept payments and not be in direct violation of the guidelines.

Which apps are allowed to open the browser for payments? I don't think even Netflix isn't allowed to do it. They just say "You can't make an account in the app" (paraphrasing) on the sign in page.

I'm under the impression anything done outside the app doesn't really fall under App Review territory. Embedding a UIWebView is considered in-app, and an embedded SFSafariViewController has slightly different rules.
