I might not be understanding the idea correctly, but I don't think the
<fs>_args structure can be mapped into an uio in a reasonable way.

The most evil fs I could find so far is umap.  struct umap_args contains
two pointers to arrays of u_long couples.

Packing it up into a uio would mean sys_mount itself has to know about
how umapfs store they mount data, which kind of defeat the ability
for sys_mount to simply call VFS_MOUNT() for the mounted device and be
done with it.
