I think, that having Samba4 ready for the time when M$ will force its 
customers to move to AD is the crucial point.
Making OpenLDAP multimaster replication reliable is something that 
OpenLDAP developers weren't able or wanting enough to do so from years. 
Multimaster replication is an important point in Windows AD -> Samba4 AD 
migration, and interoperability.
I think we SHOULD accept, that the Samba3+OpenLDAP to Samba4+Heimdal+??? 
will be a harder one that the Samba2+OpenLDAP to Samba3+OpenLDAP was 
(because it wasn't touching any of the non-Samba attributes).
IMHO we will  have a lot smoother migration path, if we (running 
Samba3+OpenLDAP) would do an inventory of what other LDAP dependent 
services are we running, and develop plans (and if needed patches and 
scripts for them) on modifying them to use the new schema. And when the 
time of switching to Samba4 comes we could do that more easyly.

Thanks for reflecting on it.
