Need to think about this some more. While it's true that the back-hdb/mdb
backends already have this information and can easily provide it, it
introduces new security concerns that sysadmins would have to be aware of.
I.e., clients could use numsubordinates to discover the existence of entries
they are not permitted to access. Which means sysadmins would need to add new
ACLs specifically for controlling access to numsubordinates.
If we just add the feature, and sysadmins aren't aware it was added, then they
have a security hole.
