Landscape photographers still use light meters, studio photographers almost certainly do in many situations
If I want to shoot a landscape and meter then use a big stopper, LEE filter, you have to meter, decide and set the shutter speed and aperture then fit the filter, if needed re meter AFTER removing the filter and fitting again
With a hand held meter the filter stays on the camera, and you are able to chose varying aperture/shutter combos from the meter at a glance
Say I chose 1/15th of a second at f8, I simply look at the LEE filter app and see that with a big stopper I need 1 MINUTE, and so on
Meters are so useful in photography they are available and sold in their millions today, they have never become out dated
