Right, versions are massively overrated. (Many people think they can transfer the knowledge they have gained about software versioning to protocol versions. Totally wrong.) The reason I’m replying is that, for EST-CoAPS, the situation is even more complicated, because CoAP has a standard discovery mechanism (which is incidentally fired by /.well-known/core), and EST-CoAPS also defines everything that is needed to make that work for them. So there already is an established way to obtain the server-defined entry point URIs to the various services. The /.well-known/est stuff mainly seems to be there because there is a belief that implementers in this space want to nail down everything and won’t do the discovery. Grüße, Carsten
