Vault.hashicorp.com/agent-inject-status <--- What does this do?

Hi. I’m new to vault and trying t figure everything out.

Looking at the official docs and various blog posts, this annotation vault.hashicorp.com/agent-inject-status keeps popping up, but I cant really seem to figure out what it does.

According to the docs it says.

blocks further mutations by adding the value injected to the pod after a successful mutation.

I figured maybe that it would make the secret auto update in the pod when creating a new version of the secret in Vault. But I left the annotation out and the secret still got updated in the pod.
