Let me do a second try...
If you believe that there is no need to garantee people to NFS mount /usr
or anything that comes SUID/SGID to one of the system accounts, you don't need
to specify numeric id's for anything than root.
However, not specifying the numeric ID for "nobody" will introduce a big
potential security problem when old (outdated) program implementations like gnutar
or pax try to unpack TAR archives that conform to POSIX-2001 and hold users with
numeric IDs > 2097151 whily unpacking based on numeric IDs (e.g. because
the the passwd file is missing the right entries).
