While that is not the worst option, our current UX is similar to Shopify, where there is an accordion component with multiple options: PayPal, Credit Card, Apple Pay, etc..
Stripe wants to fetch a premium with this feature. As such, they should bite the bullet and allow merchants to integrate PayPal as a secondary option (similar to how Apple Pay is displayed).
I will say that this is a pretty nice improvement from the modal Stripe Checkout that has been around for several years.
