mount(8) already states:

DIAGNOSTICS
       The error "Operation not supported by device" indicates that
       the mount for the specified file system type cannot be completed
       because the kernel lacks support for the said file system.
       See options(4).

I guess another sentence could be added indicating that kern.securelevel >
0 prevents autoloading of reqd. FS modules resulting in the same error. (Note
that securelevel(9) already states this explicitly.)
