I think you're overthinking it. For starters, at this point I for one don't care either way if a future iPhone has a notification LED or not, so long as I can turn it off and never have to use it. I might even welcome it, because it'll finally shut people like you up, and put an end to 2+ year old threads being dug out and revived constantly to pointless rehash this same issue, over and over.
That said, what you see as "denial about deficiencies in iPhone" is actually just people questioning what we see as a deeply flawed user experience paradigm, and our intrigue at how some people cling to such a deeply-flawed paradigm and think it's the best thing in the world.
I experienced the LED notification light, back when I had numerous pre-iPhone smartphones: from the Treo 600, 650 and 700P, to various Blackberries ranging from the original 950, to the 7280, 7130e and 8703e. Ultimately, I tried them but disabled them off when I could. I saw little point in a blinking light that would nag me every time to interact with my device to clear my new messages so the light would stop blinking... only to start blinking again minutes or seconds later with something new. And if I ignored it, it would just keep blinking... not providing me with any new meaningful information.
I came to realize that the light simply fed negative, addictive behavior, even to the point where it would distract and exclude me from engaging in more meaningful activities. And I firmly believe that the pro-LED crowd on here attacking anyone who dares disagree as being "in denial" is pure proof of that... negative, manipulative behavior to force others to get on the defensive for simply having a different viewpoint.
Interactive, meaningful notifications on a screen are a different animal though. They aren't demands for action. They provide information, and you make the call as to whether you want to do something about it. If not, no biggie... and the phone isn't precluded from giving me new information if I choose not to act on previous events. To me, that's infinitely more useful and the interaction is more constructive than destructive. So much so that the "bother" of having to tap a sleep button now and then to see if I missed anything is worth the added benefit.
Anyway, I hope Apple appeases you soon so you can stop bashing others just because they don't share your addiction. But I'm not holding my breath. Apple tends to be more about interfaces that provide potential for positive user experiences, not negative or ambiguous ones.
