I may be missing something, but why do we even need a new option for
the command that is known to always produce textual output?

As you said "Oops", the first example that shows a string of digits
prefixed by a minus sign for input "2g" is buggy, and I think it is
perfectly reasonable to fix it to show a stringified representation
of 2*1024*1024*1024 when asked for "--int".

What am I missing???
