If the workflow is enough of a hurdle for you, that’s fine. Personally, the researching and fact-checking is a much bigger hurdle. Note that, unlike a normal opensource project where a pull request has to sit and be manually reviewed and merged, PRs to Framewiki are merged automatically by the system, so changes are published immediately. It’s not a normal fork/PR workflow.
I’ve looked into MediaWiki (which is kinda the standard for wiki software), but it’s quite time consuming to set up correctly with templates and everything, and this solution does the job well enough for now. Once the site is at a scale where it’s necessary and I can justify the time and cost, plus the additional risk of downtime, it’ll move over to a dedicated wiki system. I doubt that will be any time soon though.
