[Pre-RFC] DNS domains as package namespaces

How would this work with crate ownership? (This may very well be addressed in epage's prior collection of this topic.) If I add another developer as a maintainer (uploader) of the package, do I need to somehow give access to my domain?What if I later want to no longer maintainer? Do I have to transfer domain ownership too? What if I still have crates I'm continuing to maintain? Or do I have to somehow communicate with all consuming projects about the new domain? Feels like a wonderful gap for social engineering to crack in and get a few users to use a trojaned crate.
