Missing Mirrors for modeling/emf/emf/builds

Summary

This URL returns no mirrors:

https://www.eclipse.org/downloads/download.php?file=/modeling/emf/emf/builds/release/2.29&countryCode=us&timeZone=1&format=xml

This report indicates that the entire builds folder is missing:

https://download.eclipse.org/oomph/archive/eclipse/modeling/emf/emf/index.html

I believe EMF's update sites are quite heavily used so this is not good for the server.

If I understand correctly, this was caused by builds/ being added:

https://git.eclipse.org/r/c/www.eclipse.org/eclipse.org-common/+/188741/1/classes/mirrors/mirror.class.php

I'm not sure why that was added but perhaps it could be made more specific to the reason (projects for which) it was added.

download traffic from /modeling/emf/emf/builds/release/2.29 (GET with a 200 status for jar files, including content.jar which must never be obtained from mirrors) is negligible.
