So, in other words I would depend on arbitrary sites to supply prebuilt
libraries rather than getting software from trusted community
repositories? Would those prebuilt libraries be of the same poor quality
than what is offered on the average upstream site? The average upstream
site features contributed packages. Contributed by individuals. The same
individual who would contribute their packages to a community project,
provided that such a community project is available.

Not clear at all. Why would I need that library? Why wouldn't it be
found automatically when I install an application with e.g. Yum? Why
hasn't anyone created a src.rpm for it? Aha, the software is complicated
to install from source? There we have the real problem.

Only what is popular or worthwhile gets packaged by someone.
Everything else can be rebuilt from source.

Ah, cross-distribution. *cough* Who makes sure that app A from site B
and lib D from site E for distribution C work smoothly on distribution
F where inter-library dependencies are satisfied with packages from
site G? Where is the testing and quality assurance in this scenario?

Isn't that what Fedora Extras tries to target? The chance for the
community to package the popular stuff and maintain it as long as
their is enough interest in it?

Scary scenario. Even more scary when the application asks for
superuser privileges in order to perform some ordinary integration
tasks.  The scenario gets threatening when the author of the
application focuses on prebuilt binaries as primary distribution
channel and neglects the source code level. Oh, and don't dare to
report a bug to the author when you run a different distribution.
