If you count AD the KDC+LDAP is the most deployed configuration in the
world. The the problem is not in the LDAP itself but rather in level of
the manageability of the solution as a whole.
The issues you had prove that FreeIPA project is the right way to
address the manageability of KDC with LDAP in the open source. Once it
is solved you are left with unified identity and authentication source
and multi master replication that are clear benefits over the pure KDC
