I had very similar thoughts myself.

If we compare two snapshots (of the same subvolume) we wouldn't need timestamps
either, e.g.:

btrfs subvol diff <old_snapshot> <new_snapshot>

The output could be a list of files (and directories); each line prefixed with
a plus sign (for new or modified files) or a minus sign (for deleted files).

The output could be easily postprocessed using grep and cut.
