I'm afraid that the endgame for this approach is that platform XYZ gets popular or a customer of a user of yours uses it. You have to integrate it or some of your customers will leave because they have to work outside your app. Repeat ten times in a couple of years. It's a lot of work for ever diminishing returns. But give it a try, there is nothing wrong with it. You might make a fair amount of money with only the people using the services supported now.
