I see various interpretations for the "Authors" column, I, for one, interpret it more as a credits list than a list of maintainers. Therefore, I would expect that we first ask the listed individuals whether or not they want their name removed.

For the record: I'm fine with my name being removed almost everywhere (extension,json, @author tags, mediawiki.org pages, but not CREDITS files). What I care about is that people looking for help have a way to ask questions and get responses in a timely manner. This is often better done by linking to a talk page the responsible team is guaranteed to watch, instead of listing people that typically work on entirely different projects by then.

Still an open question whether we want a standardized approach, or to leave it as optional that each contributor can be listed or not, according to their preference.
