> git supported directory mapping.

Is this a "git" failure or a "Linux filesystems suck" failure?

It seems like "Linux fileystems" are starting to creak under several directions (Nix needing binary patching, atomic desktops having poor deduplication, containers being unable to do smart things with home directories or too many overlays).

Would Linux simply sucking it up and adopting ZFS solve this or am I missing something?

How is that related? I don’t think anyone would suggest ntfs is a better fit for these applications. It worked because it was a feature of the version control software, not because of file system features.

What would ZFS do for those issues? I guess maybe deduplication, but otherwise I'm not thinking of anything that you can't do with mount --bind and overlays (and I'm not even sure ZFS would replace overlays)

Snapshots seems to be a cheap feature in ZFS but are expensive everywhere else, for example.

OverlayFS has had performance issues on Linux for a while (once you start composing a bunch of overlays, the performance drops dramatically as well as you start hitting limits on number of overlays).

Nowadays the ZFS advantage for snapshots is no longer true.

Other file systems, e.g. the much faster XFS, have equally efficient snapshots.
