Well, database records are most times stored in files at OS level with a
certain file format. The point is that access to cn=config works via
LDAP like with any other OpenLDAP database backend.

Not sure what "flat files" means for you especially compared to
"database files". LDIF is just a file format. And it was a good idea to
use it since if anything goes wrong in cn=config which would prevent
slapd from start up you can edit LDIF with a simple text editor to fix
the issue.

No problem with the filename suffix .ldif because it is LDIF which could
be parsed by 3rd-party LDIF parsers.
