Yes. As example I attached the ebuild for "nano".
And the following is the diff between the ebuild for nano 2.1.4 and nano 2.1.5
(reduced: only changed lines):
------ ------ ------ ------ ------ ------ ------ ------ ------

In cleartext: 2.1.5 is deemed stable on alpha, amd64, arm, hppa, ia64, m68k,
ppc, ppc64, s390, sh, sparc, and x86 while 2.1.4 was "testing" for them.
Also two patches were no longer necessary.
Generally, updating an application is only a matter of renaming the ebuild
file to the version of the application.
But that also means, every user has to compile the applications himself (I
like that, but it takes some processing time).

If we get maintainers for the Hurd stuff, then yes.
But for that we'd still need people who maintain them, and thought it's far
less work than doing a deb package (just rename the file), the update still
has to be tested, so someone has to build it which takes about the same time
as making the deb package.
So I assume the main advantage is the high geek concentration in the Gentoo
community :)

The emacs ebuild is quite complex, so I can well imagine that building it
isn't that simple... (I attached the ebuild, maybe it can give you a look on
the difficulty inherent to emacs - the ebuild is one with useflags ("I want
that feature, but don't want this one") and custom patches).
Best wishes,
