The 4th, a Wiki, is of course more-so just Confluence, but I have seen echoes of a wiki make their way into Jira; e.g. in one place I worked, every release was a ticket that was duplicated from a previous ticket, and that ticket had step-by-step instructions on how to run different parts of the release.
You're just wrong on this, bro. Notion tries to be everything to everyone. Jira is everything to everyone, it doesn't matter what it tries to be.
