That's a better rationale, although I don't think that really solves your stated problem; as an uninformed user I am still more likely to think that iglu/iglu is the more authoritative source there. Given this, any project that wants to authoritatively own its identifier should probably also register its own top-level namespace... which unfortunately brings us back around to where we started.

It would at least be far less of an issue. I don't see anyone being confused that https://github.com/facebook/react is the official repo, and not https://github.com/react/react. It's the fact that a collapsed name is a shortcut that imbues it with this special stature. And i believe maven central doesn't even allow one-segment group names for new libraries, though clojars obviously does.
