One difference between the excellent structured https://meta.wikimedia.org/wiki/Template:WMF_Staff and the old https://meta.wikimedia.org/wiki/Wikimedia_Foundation_contractors is that the manual list kept all past information, however partial: do you think the Lua-based template "database" can scale to one which holds historical information with dates about beginning and end of a contract (sometimes repeated)?

Given WMF has greatly reduced the transparency of its staff changes in the last ~4 years, gradually eliminating all official sources we used to rely on, nowadays we only rely an hearsay and on certain public logs of privilege revocation. It's therefore harder to maintain a rather manual-intensive page like https://meta.wikimedia.org/wiki/Wikimedia_Foundation_staff_and_contractors used to be.

I'd recommend redirecting the current wikimediafoundation.org staff page to m:Wikimedia Foundation staff and contractors

I don't think that any other organization with clear 'membership'/staff criteria lets random non-organization members edit their public member/staff list.

I'm tempted to close this task as invalid as this task is phrased as a neverending "Things should always be complete and up-to-date" task (which is a very valid wish everyone likely supports, but it's attempted already anyway as far as I know).
