Yeah, we do...

http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=2&chap=1#doc_chap3_sect5

So, we're not really trying to solve a problem here; yet we can improve
the situation so people don't have to manually retype the same chain of
commands everytime or rewrite their own shell alias or function.

Yeah, I think everyone has implemented their own kind of alternative:

eupdate()
{
        emerge -uDN @system @world
        dispatch-conf
        etc-update
        emerge -uDN @system @world
        emerge -c && (
                eclean-dist -d
                eclean-pkg -d
                emerge @preserved-rebuild
        )
}

Others have worked together and put it into a handy tool:

http://weaver.gentooexperimental.org/update.html

It would indeed be nice to join efforts and have something that does to
updating what genkernel does to kernels, then get that into the
Portage tree and suggest it as an alternative to doing it manually.
