I did originally plan for every company to be able to configure their own XYZ prefix (there's a vestibule of this that you can see here by replacing `rfc` with any arbitrary acronym like `XYZ`):
The overall namespace is the org slug (`rfchub` in this case) so I was going to allow different orgs to choose the same prefix (defaulting to `RFC`). In that respect the actual globally unique identifier for this proposal is `rfchub/rfc1`. But I need to figure out some bigger features first before I add that.
