Here we currently have 40 applications; did someone map how many of them are needed to cover the functionality of bugzilla?
Create a "bug reporter" persona, then define a default home page for that persona. If we can't have multiple home pages and redirect bugzilla.wikimedia.org to this one, make this persona the default home page for everyone and let the others customise their home page in their settings.
UPDATE: this might be supported upstream one day -- see https://secure.phabricator.com/T4103
