It's not a case of ignoring it. It's a case of it's been around since
NetInfo came out. It's *far* older than a year. But NetInfo is buggy,
non-standard, poorly documented and understood, and only runs on OS X/*Step
systems unless you get a connector from PADL.
If you look at 10.2, they are *heavily* moving to LDAP v3, which handles
this sort of thing better, but unfortunately, it has to, for now, tie into
NetInfo. Netinfo is bound at a very low level to the OS, and extracting it
correctly will not happen quickly.

It's an issue with NetInfo, not any one utility.
