I wanted to host our company wiki in Fossil, but there is no way to import it because Fossil completely separates versioned project docs and the built-in Wiki function. Our git-based wiki could be imported into Fossil as "docs" but would not receive the nice formatting, GUI editor or dedicated page that the Wiki function does. There is also no benefit to manually converting it all to Fossil Wiki as some of our wiki editors work on raw markdown.md files and commit changes by git which is not possible with the Fossil Wiki; everyone would be forced to use the online editor only, whereas currently we have a choice of markdown or Gitea's editor.

Found a link to the Fossil forum thread I opened about this very problem of the split between Fossil Wiki and docs:
