Thread:Extension talk:Babel/Problem with local categories/reply

The only thing I can tell so far is that the former is inserted by et similia, while the latter is used by the #babel parser function.

Edit: according to the [//git.wikimedia.org/blob/operations%2Fmediawiki-config.git/e0a59c6de35f3547e860483d5462b858e5e91a9c/wmf-config%2FInitialiseSettings.php#L11679 configuration file], the canonical version is os:Category:User os-0: we could either change that, and use the internationalized category only, or viceversa. Eventually, every obsolete babel template should be deleted in favor of the parser function.
