Thank you

This would be great. Will take a look soon. squashfs and ext4 still are in the works...

I have a read-only NTFS implementation brewing along which even has a limited write support (= filesystem generation). By limited I mean not implementing journaling: write-once, i.e. what formatting a partition does + allows overlaying files at write-time.

I'm not planning on implementing writes via journaling, but if someone wants to implement that I think I have a solid base by supporting marshaling NTFS data structures in both directions (not just reading).

My implementation is of some quality, it has in-memory block device shim for testing purposes and once I've generated the FS in-memory, there's "chkdsk"-like test suite that validates the testing in-memory block device's content from the read layer. I even have tests validating the MFT mirror.

I'll keep you posted once I make the repo public.

That generally is my approach as well. The qcow2 implementation in process basically treats it like a regular filesystem, doing writes. It doesn't bother with multiple layers and backing files. Some day, perhaps, but the vast majority of use cases that I see simply want to write and be done.
