IIUC with BtrFS while it is possible to easily undelete a file or ordinary directory if a snapshot of the containing subvol exists, it seems that it's not elementary to undelete a subvol itself, because all subvols are under the root-level subvol (id 0 or 5, see my other q) but even snapshotting the root subvol will not snapshot any subvols under it. So is there any way to undo a subvol delete? [If no, then ordinary users should probably prefer regular directories to subvols.]
One solution is using snapper instead of using btrfs directly. Snapper can automatically take a snapshot just before taking/deleting snapshots. So, if you delete a snapshot by mistake, it's still alive.
