It most certainly is an unecessary facitly at the base-line level. The
query mechanism is not something that is needed at the base-line level.

I don't think it does if you mean at a base-line level you will required
a mechanism like LDAP or WebDAV. Is that what you're trying to say? If
so then I couldn't disagree more.
Anything information required to deploy an application which may require
information about given artifacts can be stored in the repository
itself. If you are saying that attributes for artifacts are to be
primitives in the repository then I certainly disagree.

It's simply never going to happen and there is no need for it to. I
highly recommend a reading of Syperski's Component Software. It serves
not only as a technical guide but clearly gives reasons why multiple
standards exist and why each one can thrive.

I don't think so at all. Competition is a good thing, a great thing in
fact. You can't stop and there will always be different implementations
for personal, political, and practical reasons.
