To me that approach goes against the original principles for agile, especially "Individuals and Interactions over Processes and Tools". I'm not a huge fan of highly structured Agile and scrum processes. But I think the best agile implementations come when teams have ownership over their own agile processes.

And if the team truly has ownership they are responsible for their success or failure. Sure, their process may be objectively bad, but that doesn't mean a better process should be imposed from outside of the team. The team should have some level of trust to fix it.

I also disagree with your three points being hard requirements. They may be really good suggestions for teams doing scrum, especially in lower trust environments. All three are specifically for scrum, for instance they lose meaning if you aren't doing sprints. But that's just arguing semantics. Fixing compromised scrum isn't strictly necessary if the team can be successful by dropping scrum.
