For breaking changes regarding the API/schema(s), yeah definitely, but the majority of complaints that I've personally been seeing are regarding the UI, and they seem to be coming mainly from people creating agents using 100% the UI. I mean... I have the entire dashboard recreated at this point, and my dashboard hasn't been breaking as they break their own, so it's not bothering me unless the API changes in a way that breaks my app (which HAS happened before).
