I think this might be a little restrictive.

A NT filesystem doesn't have to operate solely in kernel
mode.  The kernel mode component is free to delegate work
to a usermode component if it chooses.  (In fact, if
I'm not mistaken, Microsoft's webdav filesystem driver
works this way.)

I believe boot filesystems have special requirements above and
beyond other filesystems.  (Like freeloader has to understand
enough of it's on disk layout to load a driver off of it.)

It is true that a filesystem that has a usermode component
can not be used as a boot driver.
