We already know that's by design. But now we have a reason to search for @media eg to search for media queries then it would be useful for that search string to not translate to xen property.
Luckily all default templates with media queries contain enableResponsive which is best practice. But that infers that all media queries will always be related to responsive design. They might not be. Or there might be cases where you need to force a behaviour in a style where responsive is enabled or not.
