using --human-readable option, example:
That's too long to type
It's completely OK to make the option shorter and make it consistent
with other parts,
(BTW, fi df uses -h, no long option, why not keey consistent with it?)
but IMHO, isn't the bash-completion script a better solution for all the
btrfs subcommands and options length?
Complicated commands like git have a quite good bash-completion script,
and with it
option length is never a problem (except some case in git config, where
some options can't be completed).
Thanks,

and the idea was to add all the long options
that force the specific unit base, ie. --kbytes/--mbytes/..., --raw,
--si and --iec. We can possibly make the human readable the default
because that's what I'd expect to see to have a quick overview and can
use the other options otherwise.
The geopt parser accepts short options if they're unique, so --kb or
even --k works as a very convenient shorcut for frequent commandline
use.

The values should be also aligned to the right.
