I've even checked images that were a bit blurry thinking SR hadn't locked, but the EXIF indicated it had locked...
The thing is everyone was moaning about the lack of a fast AF lock despite the fact that it was useless to have a fast AF if the SR was lagging way behind. Now that the SR is ready in most cases before the AF has locked it means that you can if you need to just point and shoot. In some circumstances particularly timid wildlife you just don't get that split second for the SR to kick in.
Don't forget also that the K5 keeps the SR spooled up for a fair amount of time after a shot, about 5 seconds, so if you have to take another shot you do not have to wait again for it to spool up. If you half press the shutter the Sr is active for as long as the meter is active. So while you are composing again the camera is ready to use. If you recompose and move the camera the SR goes off and comes back on as soon as the camera is still. On my Kx and K7 it takes a good second for the Sr to spool and as soon as you take your finger off the shutter it turns off.
If you are in a blind on a tripod then I agree, If you are doing macro flower shots then Ok this is not important, but for walk around wildlife and maybe sports action I think this is a big deal.
