I'm certainly not going to dispute the ntfs-3g developers, but I had
had in mind these comments of Linus Torvald that I had just come across:
"People who think that userspace filesystems are realistic for anything
but toys are just misguided.
fuse works fine if the thing being exported is some random low-use
interface to a fundamentally slow device. But for something like your
root filesystem? Nope. Not going to happen."
https://lkml.org/lkml/2011/6/9/462
Linus sometimes exaggerates, and in any event, external USB storage
devices are (generally) somewhere in between "your root filesystem" and
"some random low-use ..."
A quick search turns up this:

which I haven't had a chance to read.
