When you run deity on a bo system it will consider all installed packages
with this screwy depends setup to be broken and will complain bitterly.
There is very little I can do about that without weakening the depends
checking. I hope this will not be a problem, upgrading from bo with Deity
will be okay, only running deity on an all bo system will have issues.

This is exactly why Deity will never match a depends against the owning
package. We handle all depends in the same way so if you say that 'A
package may not conflict with itself' then you are also saying 'A package
may not depend on itself'. Since conflicts is just a form of depends.
