I was mainly thinking a simple table like:

        Filesystem      Mount             Mount-rump      Status

        FFS             mount_ffs(8)      rump_ffs(8)     stable
        NILFS           mount_nilfs(8)    -               experimental
        LFS             mount_lfs(8)      rump_lfs(8)     unstable

Or something along those lines.

Agreed. As always, someone just needs to write those. In most cases this
likely requires special expertise about a particular file system.

Though even few general paragraphs would suffice, I think. File systems are
big enough projects that almost all of them have design documents and other
material that could be listed as pointers to further information.
