Hi Thomas, sorry for being that late... thanks for your comment either way! I like your approach getting dummy data via a placeholder API. I really do! But... at that time... for me it's hard to believe, that creating and furthermore using the API is an easy-to-do task. I think the main reason for non-existant decoupling in real world examples in many cases is the effort for implementation. So I'd say the best solution might be the easiest one with less effort.

But let me know if you have other experiences regarding that. Might be interesting!
