This isn't a perfect solution, but maybe instead of projects.yml there 
could be a `registry.yml` project that would (of course) have all the 
project.yml "in-tent" projects, but also merge in external project 
requests for namespaces?

Say there's an LDAP aaS project, it could ask to reserve "directory" or 
whatever and have a reasonable hope that when they're tented they'll be 
able to use it. This would help avoid having multiple projects expecting 
to use the same name, while also not meaning we force anyone to use or 
not use some name.

Effectively, it's a gerrit-backed version of "dibs".
