That’s an expanded list, but it’s still incomplete. I won’t enumerate them all here, but off the top of my head, all of “Elements” (about 15 modules), all of “Navigation”, some of “Helpers” (including “locale”), etc., etc.
Beyond the fact that we’ve been using many of these, many are dependencies to your other published modules. Moreover, non-publicly available, recent versions of these are module dependencies to these other published modules. This is an “all or nothing” thing. Holding the source back to some modules breaks the open source covenant that Atlassian has previously sworn to all of us that it would uphold.
