I recommend to read such MLs via news.gmane.io (as I do). No problems today.

My proposal is to check all fields of current-context. Like this:

--8<---------------cut here---------------start------------->8---
# kubectl config view -o jsonpath='{.contexts[?(@.name == "docker-desktop")]}'
{"context":{"cluster":"docker-desktop","user":"docker-desktop"},"name":"docker-desktop"}
--8<---------------cut here---------------end--------------->8---

This includes the name of the current context ("docker-desktop"), and if
the user switches to another context, or changes an attribute of the
current context, it will differ.

Yes, but we cannot check everything. Compare it to an ssh connection,
which uses a Host entry in .ssh/config. If a user changes the Hostname
part of that Host entry, it isn't detected either by Tramp. The user is
responsible for this kind of changes, and the consequences.

And remember, this discussion started because you were concerned about a
changed namespace, nothing else.

My proposal avoids to store sensitive data. The authentication token
you've mentioned is part of the Users config. We don't see it anymore
according to the latest patch.
