I personally don't think that forks claiming to "provide"
something is really a good thing to encourage; ISTM that
saying a package *conflicts* with another is more accurate,
e.g. distribute Conflicts-Dist setuptools. I also think
distributions should say they are obsoleted, rather than
allowing other distributions to obsolete them.<br>

Obsolete distributions won't say they are obsoleted, unless they
receive further maintenance. However, if the distribution is
obsolete because the maintainer has lost interest, they won't
receive further maintenance.</div></blockquote><div><br>(We've been over this before, the last time this discussion came up on the Distutils-SIG for a previous Metadata PEP a year or two back, but here goes....)<br>
<br>Obsoleting a package is for handling renames and support transitions. For example, if it actually did anything to do so, I'd mark RuleDispatch as obsoleted-by PEAK, the Pylons folks might mark some version of that as obsoleted-by Pyramid, etc. To put it another way, marking a package obsolete is part of deprecation and replacement, not an unsubstantiated third-party claim about the maintenance status of an unrelated project.<br>
<br>If a package is *actually* dead, there's no real point to declaring that something else obsoletes it, and certainly no reason to put it in metadata form. Otherwise, we could have Twisted claiming to obsolete GEvent and vice-versa at the same time. Which one should an installer believe? It makes no sense in a standard where the project's maintainers can say whatever they want about somebody else's project. The scope of authority for automatically-consumed metadata should *only* encompass the project that provided the metadata.<br>
