The problem is, for bigger wikis or wikis with more coordinated, large-scope projects, chat is absolutely crucial. Whether it's Slack or Discord or IRC back in the day, you can't do much apart from piecemeal edits using only talk pages, article comments, forums, Discussions, etc.

Personally I love Discord but I completely sympathize with the concern that it's off the grid, so to speak. But unfortunately there are no better alternatives; again, unless it's a smaller wiki, or one with a more individualistic editing culture.
