Well it already works and has been since 2019. Personally I prefer to keep communication within the app at least until the first date. But 10 euro for at date and a drink is reasonable for most people. I think it’s a nice service that the app setup the date and streamlines the important part. Tinder streamline the non-crucial part of just browsing people. Tinder is not really solving a dating problem, it’s solving a social validation problem.
