If the insert fits in the compartment you are no more likely to lose it that any other part of the camera. If it is cheap enough to replace it will be no more annoying in the unlikely case you do lose it.
(Maybe I am odd but in three years I have lost no body cap, lens cap, hot shoe cover, etc. But I still prefer designs that allow for no removable part that can potentially be lost.)
Yes, but SR is quite like breaking the sensor, or shutter. It's an essential part of the camera to work properly.
Now imagine not being able to use a K-r 5-10 years in advance because you can't find in the market a damn piece of cheap plastic to fit AA cells into? Pointless.
Also, consider that a DSLR market is worldwide, and cameras are meant to last. There are professionals and pro-amateurs everywhere. Finding spare parts might be easy if you live in US/EU, or in a 5 year window. It sucks if you live (or are working) outside those places, or trying to use a camera that is more than 5 years old.
At least personally, my reason to get a Pentax was being able to use their legacy gear. How good is being able to use 20 year old glasses if you can't shoot your camera because you lost/broke a piece of plastic?
I'm afraid because I know replacing those small parts (li-ion batteries, battery inserts, viewfinders, protectors, grips, etc.) is a damn headache when you need too, which is usually when your gear is some years old, or when you are deployed in the middle of the Amazon Rainforest and actually need it the most.
