mgmt.py: should privacy be checked when changing list name?

It is possible for lists to have a mix of public and private emails, but this is likely to be quite unusual.

Would it make sense to check email privacy against list privacy when changing list name?

If a public message is moved to a private list, that will expose the list name to all users.
Does that matter?

If a private message is moved to a public list, it won't be visible to the public, but probably defeats part of the purpose of changing the list name.

Maybe the code should insist that the privacy setting matches the target list setting?

Start by reading mgmt.py around the code that changes a list name and identify how list and email privacy are represented. The issue needs an agreed rule for mismatched privacy settings before implementation can be considered complete.
