Hi

Yes the registry should generate them, but what with thin Registries.

Only we as registrar have the contact data. So we don't have a registry 
generated roid.

I can generate on but the rdap profile checker require me to register the 
suffix at iana.

Eg 
1234567-IX

If i don't register it we got an error the we use uncorrect value.
"Globally unique identifier not registered in EPPROID"

At the moment we let it empty and got a warning instead of error.
