Well perhaps I was fortunate but I did not see the problems you saw or for that matter any of the "issues" that Pentax said they were fixing in various releases. Who knows under what conditions, combinations and permutations these things were happening from camera to camera. I see no difference in the way that 1.04 functions and the way any other from since 1.01 has functioned. Must be the combinations that that had selected of various options. My point for saying that is that trying to test under every possible combination of menu setting lens etc etc becomes a massive task and I will bet that they have a standard test protocol they run to cover what they think will be the most appropriate combo of settings and then release the firmware for general release. Then they react to issues reported. Like it or not that seems to be more and more the way of the software/firmware world: test it for basic and critical functionality and let the users find the rest of the more subtle issues.
As far as high risk resulting in "turning the camera into a brick" seems unlikely and I haven't seen anyone on this or other forums suggesting that has happened to them. Also, highly unlikely that the changes they have made to date would be impacting the protocols that would allow remote interfacing . . . if they have then the changes are much more significant then they have let on. A bigger issue for getting these apps is that the apps folks expect an ROI and the number of Pentax users who would pay for this may not justify the effort . . . just like we see in other third party accessories . . . or lack there of.
Do the masses need placating? Perhaps I missed that ground swell. I am curious that you would see a longer shutter time as a goodie given we have 30 seconds and bulb.
