I have had a hard time seeing anything beyond actual scrum as being aligned with the original agile principles. Those principles are still how I tend to think... and thus be frustrated by any process that is ___ agile. The word proceeding agile always seems to mean "not" in implementation.
Shortly after I did scrum training many years ago and my small team began to outpace all other teams where I was, a new PMO was set up to turn every team into as efficient as mine. The result was that we also became slow with the process overhead and lost the advantage.
Maybe... maybe the principles can be applied regardless of framework, if not thwarted. 🤔
