Subcategories for Category:Open support requests for MediaWiki
Thanks for the Support/Open requests link. It is useful but from it I'm guessing that no notification is triggered unless you are added as the responsible dev in the Support-template. If there is a good master list for who the default dev is for different extensions then that would be easy to add but I would e.g. have no clue whom to assign as dev for the Echo-messages.
The main point remains though that there should be some process by which the responsible teams (thinking mainly WMF) get notified about issues relating to their extensions. Otherwise the solution is the current one where forgotten requests here end up becoming bugs in bugzilla just so that they get some action. That seems like a somewhat backwards process, not to mention that it results in potentially months of delay whilst the messages in question are untranslated or mistranslated.
