ldap_delete: Server is unwilling to perform (53) what does it mean? The schema is not used by any data on the server. I can use slapmodify to remove it after server shutdown, but that kind of suck and not much different, or even worse than editing conf file?
Delete support for cn=config in many cases is part of the OpenLDAP 2.5 release vs OpenLDAP 2.4. It may be simpler to use ldapmodify to adjust the incorrect schema elements. Failing that, you'll want to slapcat the cn=config database, fix it by hand, and re-import via slapadd.
