User and password is not needed for ident auth, empty hostname is
documented as using the unix socket.  And the documentation tells:[1]

| These URLs follow RFC-1738, and usually can include username, password,
| hostname, database name as well as optional keyword arguments for

So they _can_ include, not they _must_ include.  Also there are examples
of this usage.

It is valid in practice, otherwise it would not work in the first place.

No, the idea is that the user have all right to change it to whatever he
wants.  You can use ucf to do this task of merging config files.

Well, I don't think so.  You can yourself refer to the ctte or I will.
