This whole debacle is the perfect advertisement for microkernels. The only reason Kent needs to coordinate with Linus is because filesystems need to live in the kernel. FUSE is second class. Imagine how much easier this all would be if linux maintained a slowly evolving filesystem API, and all bcachefs had to do was keep up with it.

It is indeed a mistake to target Linux, as it guarantees the majority of effort will be spent tracking Linux, rather than working on the filesystem itself.

There are far better options such as FUSE or the filesystem APIs in other operating systems like Netbsd, Haiku, Genode or even ReactOS (and Windows NT).

Some of the best filesystems such as OpenZFS, HAMMER2 or Lustre are developed outside of Linux.
