It would be worse for bcachefs and the kernel if they parted ways. The Linux kernel does not have a feature complete alternative to APFS. Apple, of all companies, is beating the Linux kernel at filesystems. That hasn't happened before.

This is demonstrably not true. Kent brought Bcachefs to fruition and got it upstreamed. Wireguard was also one guy. The cryptography used in both, also 1 guy. There's an argument to be made that given an elegant, well designed system, we should assume it came from a single or a few minds. But given a system that's been around for a while, you would be right to assume that a lot of people were/are involved in keeping it around.
Yet Linux has better tested NFS, CEPH, a stable ZFS target... I think the opposite is still true, apples golden goose of an fs is still basically their NTFS implementation
