I helped resurrect this to support Windows 10 a year or so ago. It works, but because of its reliance on Dokany (a FUSE-like usermode file system library), there are a lot of ways it still doesn't work perfectly.
It was a lifesaver for me when I was doing development on embedded Linux devices (Pi/Edison et al). But if you're not tied to remote hardware, WSL is an infinitely better, faster, much more reliable dev process.
The biggest issue I ran into with win-sshfs was its tendency to bodge git repo status if you maintained the repo on the mapped folder.
