Thanks for the PR, but:
- please follow the style guide
- use
notecallouts, notwarning - small but important detail: don't deprecate the annotation except in the well-known list. Deprecate setting it.
- It'll have been deprecated "since Kubernetes v1.32", not "in v1.32+"
- use
- we should also remove or reword all places where we recommend setting the annotation

Omit this, and reword or remove the earlier text:
To enhance the security measures around Secrets, Kubernetes provides a mechanism: you can
annotate a ServiceAccount askubernetes.io/enforce-mountable-secrets: "true".

Because this PR adds warnings (as in: warning-level callouts), and we try to be really sparing with these, I suggest we don't merge this yet. |

The point of having a customized anchor ID is to make it easy to reference this section or subsection. In that spirit, I'd suggest we use a shorter ID which is
unique and clear enough in this page. For example, #additional-annotation.

I don't agree about the point. My intention here was for existing links to stay working.

Actually, in a page about good practice, maybe we should simply be recommending using namespaces as trust boundaries?

Yes, IMO this section should be replaced with the following but I’m not sure how this impacts users who may have bookmarked the old section.
Restrict Access for Secrets
Use separate namespaces to isolate access to mounted secrets.
