I understand.

I assumed that preserving file owner would be a normal feature and
would not require additional explanation.
One use case would be updating a file in a save way when you have
write access to that file but not to anything else.

Also, according to Ted, a lot of app devs get saving a file in a safe
way wrong. So I'm asking what the recommended way to do it is. Is that
strange?
