Moot point, as laziness is the primary reason why Joe User chooses an
everything-install in the fear that manual selection of packages would be
to complicated or time consuming. Despite the availability of tools like
Yum, it's still considered too inconvenient to add missing pieces after
installation (and system-config-packages is a dead end with regard to
adding software to an up-to-date FC). And do those people only install
everything, or do they also use everything? Where is the benefit of users
who install everything but use only a fraction of the packages? For most
of the Extras users it makes no sense to install every package from
Extras.

Does the same "someone" also burn complete Fedora Core Updates onto a
separate DVD? That could also be done with a mirrored snapshot of Fedora
Extras today. But as pointed out above, Joe User most likely doesn't want
another DVD of packages from which to use only a few.

That's why fedora.us started with a mandatory QA process which included
reviews and approvals by two different persons after verification of
source tarball checksums and the recommendation that they are to be
compared with packages from big/well-known distributions, too. But I
agree, unless a packager follows the source code changes done by the
upstream project with every release, there is the risk that an upstream
developer goes wild and tries to introduce malicious code if it's not done
by a hacker who breaks into a download server and manages to fool the
packagers and the community. If you believe in threats like that, you
belong to the target group of Fedora Extras commits-list, where you
can observe CVS commits.

Well, in a community project, anyone who has strong interest in a package,
which is found to be broken, can volunteer as the one who provides a quick
fix.

Bad. Unless I'm misinformed, hopefully we still plan to have FC4 Extras
ready together with the release of FC4 or shortly after. For that we would
need a mass rebuild at least for FC4 Test3, though, to catch remaining
packages which don't compile or fail at run-time and which have not been
checked by their owners due to lack of a Rawhide or FC4 Test installation.
I also think there are a very few package owners still missing.

Fedora Extras Development is used to prepare packages for FCn+1,
currently. And once more, a user, who _depends on a package_, should
invest some time in making sure the package does work in FCn and continues
to work in FCn+1.

Packages, which come out of Core and effectively are "dropped on the
floor", need to be picked up by the Fedora community.  And Fedora Extras
development is open enough to allow for participation, and monitoring
of development done by others.

Start with a set of packages which you think are not stable or not good
enough. File a bug report for each package.
