Problem of non-free name use of orgs / Feature-Request

[Timmmy-nlb]

Github is a victim of its own success:
As an enterprise user (EMU & co ), you still have the problem of being in the address space of the public github.com.
As a result, you can't freely choose your organization name - if it's already in the public domain, you have to use a different name.
This is quite annoying if you have a specific naming scheme.

The following suggestion could help here:
The slug name is used as a mandatory prefix, with a hyphen as a separator to the actual organization name. however, this will then also be blocked for others.

Example
slug of Enterprise: hhk
Orgs: hhk-org1, hhk-org2, hhk-org3,...
Blocking on "hkk-*" for all others
