For those of us who ran small-disk NFS workstations back in the day having the split and a common /usr was no quirk and very useful. (There were also diskless (Sun, OpenFirmware netbooting) workstations: common /bin, /usr, but per-machine /var on the NFS server.)

Yeah, except if you have a fleet of several hundred or thousand workstations to provision. "Cheap" is relative, especially if you're an academic institution.
