In the most common git setups, you never force-push to master - so a coworker can't rewrite history of master branch. Forges have protection rules, but even if your hosting does not, then the "git pull" will throw a ton of errors after history rewrites. So both fossil and git are similar in that regards.
On the other hand, unpushed branches can be rewritten any time in git.. but this applies to fossil as well. If you have not pushed your fossil changes, it's just a file on disk - you can delete it without pushing and no one will ever know you had intermediate version. Or work in "git" and only export to fossil (or svn or cvs or whatever) once things work.
