What issues do the pallets maintainers have?

This is HN not Reddit, so I will just say I personally don't like him and talk about sys.argv.

Nearly every script I write only requires something like the following:

    for arg in sys.argv[1:]:
        if arg == '-v':
            ...
    if ...:
        print(f"Usage: {sys.argv[0]} -v ...")

In the very rare occasion that I have an actually large command line project, argparse is built in and works fine.

What I like about argparse is that it will handle stuff like --infile -v (-v means filename in this context since it's value of the infile parameter)

or -- -v (-v is forced to be interpreted as positional in this case since it comes after --).

Yeah, I would use argparse if I had to support something like that.

To be honest, the extent of my command line parsing is almost always just this:

    try:
        infile = sys.argv[1]
        outfile = sys.argv[2]
    except IndexError:
        print(f"Usage: {sys.argv[0]} <infile> <outfile>")
