We have just agreed in our team meeting that Diffusion can be made publicly visible right now, before the Bugzilla migration.

We should enable it now. It's a nice feature to have, allows to link tasks with commits [1], and quickly shows how Phabricator dominates over Bugzilla.

This will contribute to the import of more code repositories, helping the Gitblit-Deprecate agenda, and pointing the developers attention and hopefully help in the direction of the #code-review project.

A key aspect here is that @chad and @Jdforrester-WMF can lead this way both deploying the feature and taking care of related discussions and support. The Phabricator team is also interested, and I'm sure we will help out of genuine personal interest, but as everybody may understand, our hands are quite full these days before and right after the Bugzilla migration.

In addition to enabling Diffusion, please document it briefly in mw:Phabricator/Help, so we have a place to point users wondering what is it and what are they supposed to do with it (if anything).

This is now set to Public, all existing repositories are set Public. Diffusion group has been archived.

Note we're not going to import any more repos until we've settled on the callsign naming conventions.
