I think ZFS - or at least the set of features ZFS provides - is relevant at any size or disk count all the way down to a single disk in a laptop. I've previously run ZFS on single block devices, though nowadays all my personal machines use at least ZFS mirroring. Without redundancy it can't recover from damage on its own, but checksums and free snapshots are irreplaceable to me.
It doesn't have to be ZFS in particular, I'll gladly switch my Linux systems over once a proper alternative is in the kernel. But right now it's the only working, mature solution. Bcachefs isn't ready yet and BTRFS isn't trustworthy.
Yeah if there was a similar GPL blessed effort that had most if not all of the main features of ZFS that was also robust and trust-able (likely takes years of use in production) I would be all for it. Projects like RedHat’s stratis might fill this. I’m not a ZFS zealot just love what it provides.
