I don't see any reason that a mod flag couldn't be enabled to override that launcher option and say that it definitely supports stretching to anamorphic resolutions. But still, with the current setup, you have to design your mainhall on a 4:3 canvas, and it still gets distorted to 16:9, or worse depending on the monitor setup. Are we really saying that we should still have the default on a 3-monitor (48:9) setup to be stretched across all three instead of just filling the middle one properly? An anamorphic mainhall should be completely feasible when we get code to properly support non-4:3 interfaces, but for now maintaining the 4:3 AR when the content doesn't have a way to explicitly say it works in other ARs seems the way to go. This change of default behavior isn't going to be the only way people on widescreen will be experiencing any mainhalls for the rest of time guys, it's just going to handle retail and older mods that weren't designed with widescreen in mind, and have no way to be updated to use pending improved interface features.
