Checkout payment issues

Why bubble is not introducing payment checkout options for countries like India, Pakistan and where Stripe is not available.
This way bubble is losing a big market of developers where users need to integrate payment gateways for their bubble app. The bubble should work on it if they want to excel in markets where the stripe is not the option. Also, there is a very limited type of currencies types are available to choose from. Is there a way to add other currencies like Pakistani rupees in the currency class. It is making bubble less compatible with other no-code tools.
