I don't think you figured out the point I presented you. The whole point is that new API versions are rolled out because the changes that need to be introduced are incompatible with old APIs. Otherwise there won't be a need for a new API, is there? The whole reason there are different APIs is that they are already incompatible. If you could handle new usecases with adaptors, you'd already be using them. But you aren't. > I don't know what an "API Gateway" is Right, and here you are lecturing on API design and present solutions to API problems.
