I think people want absolutely IS, but don't know why..
Cameras have good higher and higher ISO..
Very good lens have a lot of light...
-> you can have enough light for fast speeds (> 1/100 or 150)... So why do we bother for IS....
I was useful when camera couldn't go (good) over ISO400.. but know, IS is more and more useless.
I see utility only for long lenses.
While it's true that high ISO performance is good on newer cameras, it's still the case that image quality is better with lower ISOs (esp. if you want or need to crop, and esp. with smaller sensors); so IS/IBIS can be useful even with short, fast primes. Unless there's clear evidence that putting IS in a very fast lens reduces its image quality, I really don't understand why people object to the idea.
I've been in situations where I'm at 1/125s, f/2.8, and ISO 8000 and shooting stationary objects. If IS lets me lower my shutter speed so that ISO is 2000, then that is a very good thing.
