IIUC, it won't slow down setuptools, as setuptools looks at it only
if it cannot find the real package page due to a misspelling. So
as long as everything is spelled correctly, it should not provide
any slowdown.

If people do misspell a package name when invoking easy_install,
they get the feature that you consider of no value.

As for performance - 30 downloads take 3.9s currently from nearby.

The same could happen to Apache, too, of course. svn.python.org
sometimes fails to restart when a restart is request on log rotation.

Any software is unreliable; to reduce downtime, you need an operator
that is available when something breaks.

Contributions are welcome. In addition to me considering it futile,
I also don't know how to implement it correctly.

How are these computed?

Ok, done.
