The unfortunate reality is that even that doesn't always help.
If operational attributes are set by an overlay without updating the
etc, they still won't be replicated.  Worse, if something else in an
changes that causes replication for that entry, these op attrs *may*
along with the other change (I think it depends on whether or not you
delta sync), making operational attribute replication entirely
unreliable and unpredictable.  Learned this the hard way with password
attributes (supposedly this has been fixed for ppolicy, but nothing
this from happening elsewhere/in other plugins).  Until and unless core
code always updates this with a write to the db, without any way for an
overlay to write to the db without updating the entrycsn/etc, this will
be unreliable.
