How bug-free is it?

I tried Dokan and CBFS (Call Back File System) a long time ago. They were both great, but I ran into bugs fairly quickly with each.

MS is actually working on their own replacement for Dokan that is called Projected File System [0]. If I understand correctly, they need it internally for handling large git repositories, so it's probably there to stay.

As far as I can tell it is not the same thing. Projected File System overlays a part of a real file system, and files are cached to the local file system.

Agree. The Projected File System is very limited compared to WinFsp, Dokany or CBFS. I have looked at it quite extensively as my own WinFsp open source software is in the same space.

Dokany, a fork of Dokan is a very active project these days https://github.com/dokan-dev/dokany

Dokan and CBFS are more like WinFsp (another project of mine) in that they allow you to create file systems rather than "disks".

I like to think that WinFsp is very stable software. I am working to bring WinSpd to the same levels of stability.

Dokan and CBFS are at the filesystem level. WinSpd is at the block device level.

Yep, but all involve Kernel drivers. Is a block-level driver less error prone by its nature?

It has a smaller surface area (4 fundamental operations).

For WinFSP (not the software in question, but the same author, and maybe closer to what you want anyway), there's a testing strategy here[1].

Thanks.
