Good. Means it's more lean. And nothing's stopping someone installing NTFS functionality with apt. I once had to add exFAT[0] compatibility to Ubuntu because I had a thumb-drive flashed in that format.
>This would be wildly slow (if it runs in userspace using FUSE)
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.
FUSE drivers are slow, but "wildly slow" is an overstatement.
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?

I can confirm this, I've played RPGMaker M{V,Z} games natively by swapping out the copy of NWJS¹ it shipped with and running it through a CIOPFS² mount.
You can install kernel modules with APT - You can even install source code for kernel modules that live outside-of-tree that are recompiled for your system with APT[1]
Leaner on the source code side. The developer wrote that nobody is building it. If it were in obvious use, they could not even propose removal, Linux promises not to break existing systems by upgrading to a newer kernel.
> Are you really trying root as exfat? Will never work. A linux filesystem must support file ownership and access rights per file, which exfat doesn’t. Linux runs only from ext4, btrfs, xfs or such.
