Use case(s) :
Sometimes translator need to find the reason why English version of a system message is changed on translatewiki.net, and they have to clone mediawiki/core (or some other repo if it is a message for an extension), go to en.json and use git blame to find out the corresponding commit. If the Change-Id is included inside the edit summary when Fuzzybot import it (rather than "Importing a new version from external source"), it will be helpful for translator.
Quickly determine which patch cause a changes of system message on translatewiki.net.
