Precisely. In practical terms, the IV OID will be mandatory.

If we're going to require givenName/surname and forbid organizationName, 
then it makes sense to do it at the same time as introducing the new IV 
OID. Then, application writers will be able to write code to enforce the 
rule that Subject.organizationName MUST NOT appear in a cert that 
includes the IV OID.

If, instead, there is a time period during which it's legal to put 
Subject.organizationName into an IV cert, and then we subsequently make 
this forbidden, it'll be harder to enforce this rule in application code.

Jeremy, I'll propose that ballot once I've seen the final wording for 
ballot 150.
