I'm not an expert dealing with PSP, but situations where a payment is validated through a "return to merchant URL" is risky and could lead to payment being captured without the merchant being notified.

Stripe abstracts away all the complexity having to deal with dozens of payments methods behind this single PaymentIntent API, which let you query the status of a payment at anytime (and webhooks are just a way to listen for updates in realtime).

There are ways to deal with that - a very simple one is a "mop up" process, as suggested by the GOV.UK Pay Service:

But then how is this simpler or better than listening for webhooks (push)? Also, PaymentIntent allows you to query its state (pull) as described in your link.
