I find this argument to be tantamount to saying English is fine, but nobody really needs it when there is French. Yes, French is perhaps older and much of English draws from French, and yes, English is more complex than it needs to be. But in the end, pretty much anything you need to say, you can say it in both French and English.

Most problems don't need a modern solution, but that isn't an argument against modern solutions for those problems. In the end, it comes down to, which would the group of people writing the code rather have, an old-style solution or a new-style solution? If both are equivalent, there's no reason not to choose the option that looks like it will be the future.
