I vote for choice "b." RFC 2798 is an Informational RFC and as part of the LDAPBIS work we are not obligated to do any extra work to support inetOrgPerson. I doubt photo is used much, if at all, in deployed directories and I for one would not like to encourage its use by adding it to a standards track RFC.
