I wonder why they keep a physical switch on the lens for IS mode. It disturbs the shooting flow, costs more and reduces the weather proof.

It can be controlled by camera body, customized to a button for fast mode change.

It can be set to an Auto mode that CPU choices the mode instead of the confusing users.

People like control. In many cases rightly so. Auto modes get things wrong,,or at least they may not do what the user intended instead doing what the camera thought the user wanted. You would think IS is a simple thing to predict though.

Having a switch does not need to affect how waterproof a lens is. The weakest link in any lens is often the mount with the camera, switches are rarely ingress points. I have kit designed to work under water with switches. As late MF as they are well designed there is no issue. Even my iPhone has a switch and a couple of buttons yet it has an IP rating.

Remove the physical button does not mean less control. Mode 1, 2, 3 can be reserved and manually controlled from body.

It has no difference as Canon moved the aperture control ring from lens to camera body.

Weather proof things is obvious,  the less openings it has, the stronger proof it will be. Apple removed 3.5mm phone jack is the best example. Yes, they can do it (water proof) with holes, but it isn't 100% safe and we users bear the cost of it (those rubber o-rings).

You can not get any warranty from the water damage even if your iphone has an IP rating.
