parser.addargument('--version', action='version', version='') I like this the best. I don't like argparse adding arguments for me. I concur. This gives me all the flexibility I need to make my programs accept exactly the arguments I want and print exactly the information I want to present.

But you had this possibility all the time!

No deprecation or removal of the simple and convenient 'version' argument is needed for this. Just omit it, and build your version action yourself. But please notice that there are others who appreciate this simple way to do it and don't need more.
