|Open||None||T186821 [Epic] Article Alerts for more languages|
|Declined||None||T188135 Determine which wikis would benefit from Article Alerts|
As a note, if you follow the #2 approach in T184304#3997523, the investigation doesn't really matter all that much. It might however reveal different ways workflows are set up, or some that can't be tracked with templates/categories, but that could be tracked in some other way.
If you follow the #1 approach, then the investigation becomes very important.
