I really want a filesystem with snapshots as the foundation of a better backup system. Bcachefs has other useful features like CoW and disk pooling (in fact snapshots weren't even on the table until recently), but in my mind snapshots are a must-have feature these days, like journaling was 20 years ago.
Unfortunately, this has been just around the corner on Linux for over a decade now, and the two filesystems that promised to deliver it are unlikely to reach mainstream support on Linux. ZFS has licensing issues, and uses too much memory for a desktop system. BTRFS tried to do too many things, and has had too many reliability issues for me to trust it.

How is zfs using too much memory? zfs can run on a 2GB server (with some swap). Any laptop would have enough memory to run it. You might want to change "zfs_arc_max" as zfs tries to use half the memory available on a system if you don't set it and don't use deduplication.
