It seems that you overlooked the below paragraph.

Quoting from the PEP:

[quote]'(...)uninstall uses the APIs described earlier and remove all  
unique files, as long as their hash didn't change. Then it removes empty  
directories left behind.'[endquote]

Let's assume that site-packages/ contained only one package 'Foo'. Will  
uninstall('Foo') remove the site-packages/ directory just because it  
turned out to be empty after removing 'Foo'? To explain, let's assume the  
RECORD of 'Foo' contains:

$ cat RECORD
Foo/__init__.py
Foo/bar/__init__.py
Foo/bar/test.py

and according to what you wrote in the PEP ("it removes empty directories  
left behind"):

$ python -m distutils.util.uninstall Foo
rm /.../site-packages/Foo/__init__.py
rm /.../site-packages/Foo/bar/__init__.py
rm /.../site-packages/Foo/bar/test.py
rm empty dir /.../site-packages/Foo/bar
rm empty dir /.../site-packages/Foo/
rm empty dir /.../site-packages/        # !!!!!

it also remove the site-packages directory!

Then there is ~/python26/bin, ~/python26/include, ~/python26/etc, etc.. Do  
you see my point?

If by 'public', you meant open source, then no.
