One person's "expressing thoughts" is another's perceived complaint... the argument about notification lights has been going on for a long, long time... if Apple wanted to placate the "thought expressers" they'd have done so by now. That they (Apple) hasn't should tell anyone all they need to know.
Some are complaining others aren't. Whether or not Apple has done it or will do it doesn't mean that people can't or shouldn't really discuss it (sure complaining per se isn't useful, but a discussion can be worthwhile for those who might be interested).
It baffles me that people buy iPhones knowing there is no blinky light and then complain there isn't one...
For most people that's likely the case for many notifications, although for many a few notifications like missed calls and/or messages and/or perhaps even emails could certainly be in the category of wanting to be notified by something like an LED to make sure those aren't overlooked at times.
