Cool, tell that to your "scrum master" next time you see him.
The key thing is that the changes have to make things better. You should be able try those things and see if they improve things.
Lots of teams use kanban, and some teams mob. If you mob as a team what's the point in standups?
What's the point in sprints, if your continously improving, continously releasing, continously getting feedback and able to forecast well without them? Your better than scrum in my opinion then.
Scrum is a bit basic these days, but it's a good baseline start from. Thats the problem with a lot scrum purists. They will never get beyond a fairly basic level of performance.
If you havent done well, you probably to reflect and work how to do it better next time.
In that case, you can also replace "Agile" with "Kung-Fu!" Actually, I'm serious. There are various anti-philosophies in art and the martial arts which say something like this.
Replace agile word with that in your paragraph and it makes sense without sounding silly.
If you've done well you've probably learned and adapted.
If you havent done well, you probably need to reflect and work how to do it better next time.
Things arnt 'proper' agile when they are not about adapting but instead following a specific process your team cant change.
