You're right for most servers: the convention
is that if the server doesn't want authentication,
it sends back an Rerror to Tauth.

Sources is a bit different: it doesn't require
authentication, but it will accept it.
This is how it can tell who should be writing
to each contrib directory, for example.

The result of sources following your lead
is that you need to use -n if you really intend
not to authenticate.
