Almost nothing is unusably bad. In VCS space, even SCCS is still better than nothing. CVS is still quite operable, OpenBSD is one of the finest codebases out there and it uses it. I actually agree you that Fossil is not a big improvement, and I guess I'll stick with Mercurial for quite a while for my stuff. But in our world of software improvements are almost always incremental, even when dubbed otherwise. I'm not trying to convince you that Fossil is an ideal tool to switch to, just that saying that it doesn't bring any improvements and then listing some problems common to other tools in the same space is a bit unfair.
