Syncrepl was untenable with non-serialized updates (which moving to delta-syncrepl helped with). Even in a standalone setup, I find that serializing the update process provides faster write times (at least with back-(bh)db) than allowing multiple update threads.
But with transaction support there could be lots of modifications in one transaction which could prevent other LDAP clients from proceeding for an unacceptable amount of time if you serialize all transactions.
