Since June all projects coming in have had their bugs & jenkins mail directed to the singleton mailing lists of the appropriate name and no Gerrit lists have been created in favor of having people setup their project watches in Gerrit directly.
Information on all of this has been documented in the Communication wiki page [0]. I would like to get the blessing of the TSC to start the removal of the old ${project}-{bugs,jenkins,gerrit} lists as they are still a source of confusion to folks.
Yes, yes, yes! Fewer lists, +1
My plan would be to inject into the various lists a deprecation mail (at a minimum every 2 weeks) with information on how to continue getting the traffic from the appropriate places and then to delete the lists in early January. This along with changing the description text on the list page to note the deprecated status should hopefully be enough to get folks to switch to the appropriate lists.
