You actually brought up a good reason yourself:
In the face of ambiguity, refuse the temptation to guess.
If you ask "give me a version argument", the question is "how is it
spelled?". IIUC, you originally complained that the spelling of argparse
(i.e. -v/--version) is not good, and that a different spelling should be
used. So it's ambiguous, in which case the feature shouldn't be provided
in the first place.

Martin
