Yes. I think it is also mentioned in the gentoo handbook. In fact, you
should not use --unmerge because it doesn't check dependencies before
removing the package.

If you want to delete a package only if no other package depends on it,
either remove it from world or use
`emerge -av --depclean <package_name>`.
The latter has the advantage of also telling you what depends on it.
