I hope you can understand that I don't consider your personal opinion
alone as a consensus. As I said, I'm willing to change the defaults
and even break backwards compatibility a bit in Python trunk[1] but I
need to a see a consensus from a variety of developers that
"--version" is the right answer, and not "-V/--version", etc. Note
that even though I agree with you that "-v/--version" is probably not
the best choice, in the poll[2] 11% of people still wanted this. So
it's not a simple decision.
By the way, we could simplify the typical add_argument usage by adding
"show program's version number and exit" as the default help for the
'version' action. Then you should just write:
parser.add_argument('--version', action='version', version='<the version>')

Where did you get that preposterous hypothesis?
Did Steve tell you that?
