Everyones experience is unique. What is a fact and has been proven time and time again is that there were differences between the two chips. Small differences, sure. But differences nonetheless. As far as the answer to your question, I don't foresee Apple going the same route. The outcry was pretty loud. I'd imagine they would avoid it if at all possible.
As far as those saying it was "stupid" and "blow out of proportion"...you can't minimize the issues of others just because it worked well for YOU. That's not how problems get solved. As far as I'm concerned if I pay $850 for my phone and my neighbor pays $850 for his phone there should be absolutely NOTHING internally that would result in my phone under performing his by even a fraction. (And it has been proven to have been the case with the differences in chips). It's simply the principle. I pay good money for a company's product, the least that company can do is ensure, based on the hardware used, that their products operate in a similar fashion.
FWIW, despite my disagreement with the whole situation, I've got the Samsung chip in my phone. I haven't experienced any overheating and the phone works just fine for ME. I have NEVER gotten more than a day on my iPhone. Those people getting 2 to 4 days must not be touching their phones, lol. I have no idea have that's possible.
