It is my understanding that as soon as you store back-config data into the
underlying database, the slapd.conf is no longer used.  So the only way to
have the new schema files parsed in is remove the underlying (back-ldif)
database and start from scratch, but I'm afraid this would not preserve
changes occured via protocol.  Or am I missing something?

This is an option; I considered that, although it might be error prone as
the underlying database should be mainly accessed via API and not manually
(and it could eventually become a back-bdb, and I envisage sci-fi
scenarios where back-config is using back-ldap for remote storage of the
configuration...;)

I concur.
