- many optparse programs use the version argument - many other programmers find this feature very convenient - dropping or deprecating this is a totally unnecessary change (I have not read a single real reason /why/ this should be done).

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.

Regards, Martin
