They do already.

In the specific case that Tarek referred to, it wouldn't: the repository
URL and -dev URL of a project changed, but the old releases weren't
changed. As a consequence, the package's "simple" page listed both, and
setuptools would chose the wrong one.

Of course, for bug trackers, this specific problem likely won't occur,
unless some software starts to automatically locate the bug tracker
for some software.

One would hope so. However, people actually leave the old sites in a
very bad shape: hanging web servers and stuff like that.
