The beauty of fuse lies in being able to make usable filesystems for all those niche filesystems out there. The drawback to fuse is that those niche filesystems need somebody with enough interest in them to write a fuse filesystem for those one-off niche filesystems. (A bit chicken and egg.)
I have written a couple of fuse filesystems for mounting older 8-bit computer filesystems on Linux. But they take a lot of work and a lot of time to debug. Which is probably why they aren't used a lot.
The common file systems have been done on fuse.
