Those threads mentioned that it behaves differently on Solaris, but
didn't say how, so I checked:

On Solaris:

     -g

         Prints the entire statvfs(2) structure. This  option  is
         used  only  for mounted file systems. It can not be used
         with the -o option. This option overrides  the  -b,  -e,
         -k, -n, -P, and -t options.

Which indeed makes it harder sale. -g is flat-out non-portable, since it
has different meanings on different platforms, and not supporting it at
all may be nicer to clue users in to the fact than it would be to pick
one way and alienate users of the other way.

But can we make it more obvious that -BG does the same as the proposal
for -g?
