All the truth.

And this is not a good idea, because numbers are reserved for devices
defined in /etc/default/tar in for example SCO UNIX and maybe in other
UNIX-es too. There are some unused (in tar) letters in alphabet yet... ;-)
'J' (bigger compression than bzip2, 'J' looks a bit like '7')?
'q' (like quick for lzop)?
I would propose [-]q|--lzop and [-]J|--7zip.
