Thanks, it should really do this check. It has already caused multiple
problems in the past where people get confused by the divergence
between both views of the world.

Agreed, this is an issue, and it's at the top of my TODO. This is
orthogonal to the problem we're discussing, though. I'll solve it by
introducing a proper "juju publish" command.

That's definitely a good idea, +1. That said, it doesn't solve the
original problem, because there are again two different places that
check to see if a charm is valid or not. We need a single
authoritative place being verified when we want to tell if a charm
exists, and that place exists and is trivial to query.
