I set high ISO myself on my GX7, when I need fast shutter speeds in A mode for fast moving objects.

If you care about shutter speeds being fast enough to freeze subject motion, which may change from shot to shot, then why are you in A mode? Being in A mode ought to mean that you don't care what the shutter speed is.

As an aviation photographer, It's worth saying that for fast jets etc, I and virtually everybody who shoots planes shoots in A Mode.

Just because a lot of people do it doesn't mean that it is the best choice. If lighting conditions are such that you are unlikely to fall below a specified minimum shutter then A mode may be just fine. If you have a specific minimum shutter in mind and your camera allows you to to set a minimum shutter for use with Auto_ISO, then A mode with Auto-ISO may be a better choice.

This means that you are shooting at the best aperture for your lens and that you are controlling DOF which can be very important. Ideally we want our shutter speeds as fast as achievable so we are watching constantly what the camera is selecting. If it falls below 1/1000 that may be time to up the ISO, or compromise the shutter speed or the aperture.

Shooting props or for panning we change to shutter priority because it becomes the most important parameter

Or maybe you should just be in M mode with Auto-ISO for the whole airshow.
