That would never happen anyway, unless you removed existing releases.

I believe buildout has an option to prefer final releases. If you 
release a non-final release (beta, alpha) and people use this option 
they won't get your version even if they do not use a list of pinned 
versions. But that doesn't look like what you want.

That's like what Chris suggested with a potential supersedes and 
replaces metadata for packages in PyPI. PyPI doesn't really support this 
yet.

I think you could simply release a package that issues a deprecation 
warning when it's in use. That way people will know to look somewhere else.

Note that there's also work done on the test runner (don't know the 
state, Christian Theune is working on it) that can report on improved 
import locations for a codebase (if you were importing from 
zope.app.component something that's now in zope.site, it will tell you).
