I think ensuring UID==GID by default allows having
automatic umask relaxation for UPGs to work and not 
compromising security, even in corner cases when the system is setup in
other environments. Besides making UPGs and permissions more cleanly
visible/detectable/adjustable on removable filesystems or tarballs
(where you can only see numerical IDs).
