I don't quite see why.  If you add an index via cn=config, that starts
an indexing task while slapd is running.  A following shutdown-restart
is not necessarily related to a desire to not run that task.

If you shut down slapd because you want to use slapindex, then you know
what you want - so just go ahead and use slapindex.  No extra flag
needed.

I suppose there could be a flag to _not_ start the indexing task when
you add an index via cn=config, so you always must slapindex.

Or a status file in the database directory.

A cn=config attribute would make it messy to swap database directories
around, since one must also modify cn=config when doing so.
