If you're emerging dependencies without -1, then yes, otherwise, no.

What makes you think that?

Yeah reviewing the output of a --pv --depclean sounds like a good idea.
Then you can add anything that's obviously missing to world before a real
--depclean. When i depclean i use -av --depclean --exclude gcc --exclude
gentoo-sources, since i like keep 2 gcc's around and I look after sources
manually.

AFAIK missing dependencies are rare as they are quickly identified by the
breakage.

I ended up rebuilding two machines, partly due to self induced
hardened/PIE/PIC pain, and also to start with empty USE and
/etc/portage/package.* files which were full of crap after many years. I
now have;
$ wc -l /var/lib/portage/world
63 /var/lib/portage/world

and emerge -pe says "Total: 1024 packages"
