For the sake of existing pod-identity users who install it manually; please mention in the docs that this will work as a managed mode; i.e. no MIC
I just verified this.

@phillipgibson are you still working on this?

Let me see if I can close the loop with the Docs team.

@phillipgibson Is the PR in the private repo merged? Can we close this issue now?

[phillipgibson]

Yes this has been merged. The initial PR was associated to the wrong docs repo.
