An "emerge -uD" will check all dependencies for updates. So that's how
one is supposed to make a full update. You most certainly don't want
all packages in your world file. This would include dependency packages
(e.g. libraries), which might not be dependencies tomorrow (changed
software, changed USE flags, etc.pp.). And when you do the occasional
"emerge --depclean", it can't take those "stale dependencies" into
account, because they are in the world file. So e.g. libraries not
linked anymore to anything would still be left on the precious disc
space, because they're in the world file.
I regularly take an editor and trim down my world file (I forget about
--oneshot very often) to the packages I want to use. Then I run "emerge
--depclean" to get rid of old cruft (to be sure, I could have done a
"emerge -pvDn world" before, but I trust myself enough not to shoot
myself in the foot).
