users can pay fees with SPL tokens
When I hear "users can pay fees with SPL tokens," my first reaction is not excitement. It's relief. Not because it's flashy, but because it finally acknowledges something that most people pretend is not true: the "gas token" step is a kind of onboarding tax that has nothing to do with the product users come with. It's just logistics. And forcing users to deal with logistics is the easiest way to make a good product feel broken.
