Does content from Workgroups need to be in a form of a wiki? Can it be a github pages, static pages, markdown rendered websites? For example, Python docs editorial board publishes our meeting notes, decisions, and list of board members on a static site on GitHub pages. This is markdown based content.
Github repo at GitHub - python/editorial-board: Communications of the Python Documentation Editorial Board · GitHub
The things that Marc andre mentioned: do those need to be hosted in PSF infrastructure? It sounds like people have been using PSF infrastructure wiki page as an advertising platform for free. To me it is even more the case that PSF should be able to curate and manage the content hosted on wiki/their own infra to ensure alignment with PSF mission, instead of whatever goes. Advertising should be a paid feature.
