Hmm, that doesn't match my experience.  I just tested with the smallest
set I ever use, @module-rebuild :

# emerge @module-rebuild
Calculating dependencies... done!

# cat /var/lib/portage/world_sets 
# file /var/lib/portage/world_sets 
/var/lib/portage/world_sets: empty

I don't think I have anything in make.conf which would change the
default behavior WRT world_sets, but here's what I have anyway:

FEATURES="binpkg-logs buildsyspkg collision-protect downgrade-backup
     fail-clean fixlafiles news parallel-fetch parallel-install
     preserve-libs sandbox strict unknown-features-warn userfetch
     userpriv usersandbox usersync"

EMERGE_DEFAULT_OPTS="--ask-enter-invalid --jobs=8 --load-average 11.2 --with-bdeps y"
