MediaWiki core has a feedback tool that is used in several extensions, including VisualEditor. It provides a form that allows the user to enter a subject line and a comment. Those are turned into signed messages on the designated talk page, using ?section=new.
This doesn't currently work with either Flow or LiquidThreads.
It also collects unwanted feedback, because at most wikis (and in some contexts), it is the only obvious method of giving any feedback at all. For example, 100% of the "software feedback" responses posted through the feedback in VisualEditor at the Indonesian Wikipedia have been about article content. Those messages belong on the article talk page.
I propose that we update the feedback tool to use simple, practical structured feedback systems. Instead of asking:
Subject: (blank) Message: (blank)
let's start by giving them a couple of buttons that lead to different pages and/or experiences:
What is your feedback about? [Page contents] [Software]
Each button then leads to something similar to the current feedback form, but with custom information at the top. For example, the "page contents" button might link to a "how to edit" page, and the "software" button might request that the user provide browser and OS information. Ideally, the buttons could be configured per-namespace.
Depending on which button is chosen, the user's message gets directed to the appropriate place (e.g., for a problem with encyclopedia article contents, the message might be posted to the talk page or perhaps a new-user friendly central board) . "The appropriate place" should be locally configurable for each possible button.
