Wikimedia Product/Component responsibility

Following below is a list of extensions we believe currently fall under Reading for triage (n.b., not all extensions will get active development support). Feel free to add discussion topics to the Discussion page.

One important outstanding question: Is MultimediaViewer appropriate for Reading given its consumption-oriented nature? Or is this actually better suited to Editing (where there exists a team named Multimedia)?

Some other notes:
 * For skins with low utilization, we in time probably should coordinate handover to interested community members (or discuss with community members practical approaches for EOL).
 * Regarding the Nostalgia skin, we believe it's only used on https://nostalgia.wikipedia.org/wiki/HomePage, so maintenance would be updating for breaking skin changes or security issues only.
 * JsonConfig, ZeroBanner, ZeroPortal - we'll need to examine this more closely. Yuri (who has deepest PHP knowledge on extensions) is now over in Discovery, Jeff (JS & Lua) is in Reading, and now Adam's managing.
 * Collection probably belongs in Services.
