It's not that ZFS doesn't have these capabilities, it's that ZFS is doing these similar checks and repairs as part of its normal operation and more. If you can't mount a ZFS filesystem, odds are a similarly borked ext4 filesystem isn't going to be repaired by fsck. I got bit by some pretty bad foot guns in BTRFS that has meant I steer pretty far away, but my understanding is these have been somewhat mitigated. I hope it continues to work well for you.
