I mean, he does have a point, but his point has a solution: do not put them in mutually exclusive groups if they aren't mutually exclusive. It seems more like this is a missing feature rather than an issue with mutually exclusive, if the desire is that `argparse` handles this in an elegant, internal way. So, yes, `argparse` has a limitation on argument groups, but `add_mutually_exclusive_group` is not the issue.
