Fossil's default mode, autosync, is more closely modeled by: git pull && if stillCommitingToBranchTip; then git commit -a; else echo "Not committing to the tip of the current branch" >&2; false; fi && git push

You can turn autosync off in which case the fossil/git push/pull doesn't happen and your commit goes straight to the repository -- still without a staging area.

This is my personal usage but, if two changes to the same file are to be committed separately (e.g., git add -p) then the commit that should have happened for those separate changes that was tested just got missed, or the commit that is occurring is untested and perhaps incoherent. That is to say, I build my staging area out of files on disk at the same time rather than building a changeset that may have never actually existed on disk.
