E&M is Lorentz invariant though, not Galilean.
This causes an issue with your starlight aberration example as well. Velocities do not add linearly (though that is a reasonable approximation for low velocities).

Yes, I know that it's not exact for high velocities. My point was just that you don't need relativity for this effect to happen.
