So I should say

"Debian should not provide eggs, period", since what Debian provides
are packages, and eggs are not?

I didn't say the egg system in inoperational. I said that distutils
setup is not operational for, for example, FormEncode: this uses
another packaging library in setup.py, not distutils setup.

I had "*distutils-based* setup.py" in mind.

This is not the same. A java .jar file is deployed by putting it on 
disk. For an egg, an (apparently undocumented) number of additional
steps is necessary, such as editing easy-install.pth.

In Java, the drawback of course is that each user has to edit
CLASSPATH to include all the jar files desired. easy_setup
makes this unnecessary, but in a way unfriendly to dpkg (and
I assume other Linux package formats).
