Sorry, but I do not think you are considering what would happen when yo=
u
have many branches with different purposes, whose commits near tips wil=
l
never get merged with each other. "automatic following" semantics like
what "git fetch" does for signed tags is absolutely necessary in such a
case, and the above are not mitigating factors at all in that context.
