well one problem is that Celery still has bugs and issues, and each new release fixes some bug of the month (it sometimes introduces new ones unfortunately). There was a sequence of releases in 4.x that each had their own game-breaking bug for us, which has meant we have been stuck for a while (I've tried personally contributing fixes to this project, and fixed one bug, but another got introduced in the same release). I would be happy about more granular releases, but I hope they could make more "bugfix-only" releases so I can make some forward progress on not having a busted task queue.
