Just curious, is anyone seeing similar things with big VM images or other

What about btrfs device subtract? That's what _I_'d call the opposite of
add. Otherwise, add/remove instead of add/delete
The opposite of btrfs device add is btrfs device delete. This really
should be btrfs device remove.
Changes from v1:
- Add support for flags to cmd_struct and a CMD_ALIAS flag which only
prints the one-line usage string
- Rearrange the command wrappers in a way that could be made generic if
We're also going to want to support aliases, so rather than adding
another member, replace hidden with a flags member.

There's an awkward asymmetry between btrfs device add and btrfs device
delete. Resolve this by aliasing delete to remove.
