I would pay for a solution that aggregates these alternative payment systems that aren't tied to VISA and Mastercard and their rules.

Wero, RuPay, WeChat Pay / AliPay, Crypto (through 3p like coinbase or directly), etc.

And handles them in nice and unified API, with hooks for subscriptions, etc. (taking into account that some payment methods do not support recurring payments, so there should be some hook to send an email to the customer to renew manually, etc.)
