IS on the lens is obsolete.

IS, or an IS switch? Optical IS still has its place and in combination with IBIS we get a lot of stops stabilisation to play with. Not sure we are fully there yet with IBIS to do away with OIS but yes, the day may come.

Not likely for long lenses.  The required movement of the sensor would simply be too great, since the magnification of the lens magnifies camera shake by the same proportion.  On the flip side, there are some forms of stabilization that can only be done in the body, such as rotational.  OIS and IBIS are different things, for different purposes.

It has nothing to do with convenience by feeling. It's simply because they cannot do it decades ago. We are used to the flaws, that's it.

Nope, it is not a flaw. Many including myself like having the switches. You still don’t answer why you want them removed, why you dislike them. You simply cannot say “Because they reduce waterproofing” with no engineering knowledge and more importantly, data to back that up. Any problems with switches have been dealt with decades ago.

It isn't hard to design a completely waterproof switch (at least in principle -- I'm not a mechanical engineer).  One obvious way to do it would be for the mechanical switch to contain a small permanent magnet, while inside the switch there are spring-loaded magnetized pins that effectively sense the switch position.  There are surely better ways of doing it; that's just off the top of my head.
