This would be wildly slow (if it runs in userspace using FUSE)
The good thing is that the kernel still includes a (better) ntfs driver

NTFS-3G through FUSE is what most people are using. It's slower, but not that slow.
ntfs3 hasn't seen that much large-scale deployment, and you don't have to look very far to find people complaining about ending up with a messed up filesystem from it. I'd put a very modest level of trust in it not eating your data.
Anyway, between FUSE, epoll, DMA, and userspace networking Linux is already enough of a microkernel to benefit from it; so when do our CPU oligopolists plan to turn their shared memory hardware into a useful message passing mechanism?

This read-write driver has been a tremendous help to me, from Linux 5.15 till now. I hope they can soon publish the mkfs tool they committed to previously as well.
