Wow, that is your retort? It is from the comics and known to be Kara's name so they kept it. Cat also pointed out the cheesiness of the Flash considering that name often refers to Flashers. However he still keeps it because that is his comic book alias. As does Supergirl. Because they actually respect the canon.
