I've read this thread on and off for a while - it's very hard to comb through 1,200+ posts to get to the various chunks of meat in the thread. This thread may qualify for a wiki summary entry that contains the definition of the problem -- which cars are affected, taper graphs and time (excellent work, btw), the response from Tesla, and perhaps any other pertinent facts/user polling/etc.
Then I thought I might weigh in with my thoughts -- from just another chicken in the roost.
When I signed up to purchase a Model S, I figured on a great amount of flexibility. The ability to update the car's software and add features remotely was incredible and was unprecedented in the industry (and really, still is except for the Model S). But I had no illusions about the hardware dependencies that exist; I was pleased to hear rumors that there were appropriate harnesses and such for the easy addition of sensors to do parking sensors and adaptive cruise control and such, and slightly deflated when I found out that a good chunk was untrue.
In the big scheme of things, this issue really doesn't sour me. I'm happy that new cars are able to charge with 33% more current at the beginning of the cycle, and that they can charge faster. I'm happy that new purchasers are able to get that performance, and that my Model X will have that - or better.
Would I be enthusiastic if Tesla replaced my battery pack gratis? Absolutely!
Would I pay even a modest fee for Tesla to give me the capability? No. I don't need it. I have 4 kids and they spend more time screwing around than it would take under the 90 kW taper.
I'm not downplaying hte needs of anyone else here, especially those who regularly travel long distances and would need to use the Superchargers more than I do... that's just their situation, and this is mine. The extra 10-15 minutes every 3 hours or so gives me time to enjoy life just a bit more, or maybe talk with others.
Overall, Tesla has been incredibly supportive of me... we struggled through the alignment issues that generated the 21" tire chomping problem, and Tesla made things right. I've had a couple of small things here/there that have popped up. Just yesterday, I received a call that my 12V battery was below thresholds and needed replacing; they called me - not the other way around, came out and replaced it -- what other car company or dealership does that?! I have the most "likes" to my Facebook post detailing my experience with the 12V replacement than I have gotten on any other post in a few months!
That's not to say that the perspectives of others are wrong; a business traveler who uses Superchargers regularly is going to grow frustrated losing a half an hour on the longer days if she must do it 200 times a year.
My opinion, worth less than $0.02...

Like I stated before(when you first started the report), the Model S battery pack report has a fatal flaw. It only seems to measure how much out of balance some Model S packs are. All it is going to do is create FUD about degradation that is not there.
Because I mostly work out of my home, my car does sit, charged, plugged in for extended periods of time. 258 seems to be my maximum after 17,000 miles. If there are tips on "rebalancing" differently, let me know.
