What I am saying is you can't sufficiently lock someone down that can logon
interactively. And from there, the forest is the security boundary, not the
domain, not the DC.

The security around domain controllers is based on users getting only network
based access to authentication/ldap/policies services. Generally read-only
except for some fairly non-consequential resources. As you bring someone into
the fold and give them access to manipulate the file system or get interactive
logon access or manipulate services the exposure increases tremendously.
