Well, the issue should be more clearly (and more simply) explained, so let me try. On the K10D/K20D, if one presses the AE-L button to lock exposure and than changes anything afterwards which might impact exposure (mode, flash, etc), the exposure lock disengages and the button has to be pressed again to relock exposure. The exposure lock also disengages after each shutter activation (each image).
According to you, this is different than the behavior of your older Konica-Minolta cameras (5D & 7D) where the exposure reading remained locked throughout any later changes until the user disengages it by pressing the button again.
You're now asking whether the Pentax way is better ("the AE-L button is fine like it is") or whether the button should be changed to mimic the behavior of your Konica-Minolta cameras ("the AE-L should lock the exposure, period").
Personally, I don't think exposure lock should remain throughout any changes. If I compose an image (locking the exposure in the process) and then decide on different course of action (different mode, different flash usage, etc), it could just as easily include different metering as well. If not, it's a simple matter of pressing the AE-L button again. Therefore, I voted for the first option - "the AE-L button is fine like it is."
