Feature summary (what you would like to be able to do and where):
Wikimedia should set up a dashboard to track the most-subscribed-to/most-tagged/high-priority tasks on Phabricator.
This would be done by making queries to Maniphest's tables since the Phabricator web interface has no way to search/sort through "tasks with the most subscribers".
Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
A tool for the WMF to evaluate popular Phabricator tasks and consider them when making development plans.
As @xavidegr commented in the proposal to "Dismantle the annual Wishlist survey system":
There are years of pending coding work to do with explicit, precise, extraordinary well-defined tickets both here (especially on the sister projects) and on Phabricator.
This thought, and my personal experience with popular tasks on Phabricator, is that there are tons of tasks Phabricator that have an extremely large following with a large number of subscribers, but they sit dormant every year and only are recognized when someone eventually comments on them, which may be a period of months or years. As a result, these are issues are not worked on and fail to be considered in the development plans of WMF teams every year.
WMF has the Community Wishlist Survey to evaluate community software needs, however that only covers features happened to be proposed for that CWS edition. There are plenty of proposals that may have high significance that have tasks here on Phabricator or were proposed in previous editions of the CWS, but happened to not be proposed for the current edition of the CWS and as a result, they may continue to remain dormant without consideration or action.
WMF needs to develop a system to track long-standing issues with software so that they can be evaluated against all other proposals in a holistic manner.
Creating a dashboard to track popular Phabricator tasks could be a first step in doing this.
Benefits (why should this be implemented?):
Better allocation of development resources towards highly-needed tasks that make large impacts.
