If manufacturing capacity cannot meet demand, then that's a separate problem that needs to be addressed on its own. But it's not an argument against releasing a bigger iPhone, IF said iPhone would improve Apple profitability. Conflating these 2 issues doesn't make sense.
Because that would be like arguing that Apple doesn't need to improve the iPhone, because hey they are supply constrained!
Do you think Apple is as cavalier in discussing lost profits as you? You think they aren't trying their best to improve manufacturing to meet demand and capture as much revenue as possible?
I don't think Apple has any problem with profitability at the moment. And of course I think they're doing everything to meet demand. The point is, if they can't meet demand today and they introduce another model of iPhone with different manufacturing requirements (nevermind design, support, etc), they set themselves up to provide a sub-paar experience for their customers. They are strong today because they are focused.
Android phone manufacturers had to find ways to distinguish their products and screen size was an obvious one. And some people clearly want a big bulky phone in their pocket. But I'd wager that Apple has studied this issue a lot more than any of us here and has chosen the optimal screen size based on their market research. A handful of people on a tech website clamoring for a larger screen is anything but an accurate sample.
So what incentive does Apple have to produce a larger screen iPhone? They are maxed out in terms of production today. Another model would require more resources and create another set of issues in terms of support, upgrade cycles, etc. I just don't see the point when they can't even satisfy demand for the models they produce.
Of course plenty of people doubted the iPad Mini would ever see the light of day, yet here it is. And it's clearly a huge success. Still, I don't see the advantage of a larger screen on the iPhone especially if, as you suggest, it's simply a scaled up version of the current screen. That means no more screen real estate for apps, just a bigger screen for watching video. That would be the only advantage. Is watching video really that much of a deciding feature?

Of course they are considering new screen sizes. After the disappointing response to their ill-conceived and awkward "tall-skinny" iPhone 5, they HAVE to do something, and fast.
Yeah, record sales is definitely what I'd call a "disappointing response." Are you that thick?

Apple have to release a new iPhone into the mix with a larger screen - customer choice is a good thing. It's obvious that some will choose a phone on screen size. The iPhone looks claustrophobic next to larger Android devices.
And Android devices look positively bulky and unwieldy compared to a sleek, slim, lightweight iPhone. Besides, if, as madmaxmedia suggests, a bigger iPhone screen was simply a scaled version of the current screen, that means no additional screen real estate for apps, just a bigger screen for watching video. That's the only advantage. Doesn't seem worth trading slim, lightweight, comfortable to hold and easy to pocket for a slightly larger video watching screen.
Apple doesn't have to do anything. They are selling a record number of iPhones. Customers do have a choice. Buy an Android if you're so obsessed with a bigger screen. You have plenty of choices. Apple has never been about "choice" anyway. They do what they believe is right. Reminds me of how some people couldn't stop insisting that Apple needed to license MacOS and create a market for clones. There were many vocal boosters of the idea. And when they finally did it, it was a huge failure. Just because a vocal minority wants something doesn't mean it's a good idea.
