I guessed as much, but I don't remember easy_install all that well, it's
been awhile since I used it.

Why would they go in dependency-links? I mean I understand that
people might do that to remove the need to direct their users to
enter a full url. But that is outside of the realm of PyPI at that point
and can be fixed in the tooling.

easy_install / pip / buildout / etc should *never* fetch anything outside
of PyPI without the *user* (not the package author) directing them
to that url, either directly via tarball, or implicitly with --index-url/--find-links
and PyPI shouldn't make that an exposed part of the workflow.
