Over time The Train™ has become the default way to deploy changes to Wikimedia's MediaWiki cluster -- for some patches that may not always be the right path. If a developer needs a change deployed *now*, or if there is a desire to deploy a change in isolation then backports might be a better path.
As with all things, some exceptions may apply. The Release Engineering team has created some guidelines[0] that will hopefully help explain when something MUST, SHOULD, or MAY[1] be deployed via the train or via backport.
Is this suppose to codify existing practice, or suggest/recommend people should be deploying things more frequently outside of the normal train? Tgr has raised roughly the same question on the talk page: https://wikitech.wikimedia.org/wiki/Talk:Deployments/Train_vs_backport.
