You ability to pivot as an individual is already limited based on your team. In fact a unilateral pivot is destructive and can inflict pain on everyone else. I'm not sure how having implicit and ad-hoc patterns of interactions is agile. Why? because you can't improve what you can't see.
I guess part of my skill as a professional is knowing how to work with my team, communicate as needed, understand whay they need to deliver business results and get them to understand what I need to deliver business results, prioritize as needed, and make sure I'm not inflicting pain on everyone else.
If you don't have that level of trust in your team members, sure, formal process makes sense. And I'm all for it if that's what's needed to deliver business results successfully. But you're then valuing processes and tools over individuals and interactions, following a plan of when and how you may respond to change over letting individuals figure it out, etc. Again, it's perfectly okay if it's not agile if it's what the business needs. But my assertion is it's not agile.
