Sounds like early 30 kWh packs have a higher than expected cell failure rate. For those that see a large imbalance in their battery stats via LeafSpy, you might want to proactively reach out to Nissan, citing the above article and your LeafSpy stats as evidence.
Nissan (and its dealerships) could not care less about LeafSpy. A customer would have to convince Nissan to check for a weak cell with a protocol they have but rarely use and I'll guess not even known about in many a dealership.

The test is called cvli
Yes, Nissan couldn't care less!

March update. 351 GID's , AH=76.68, SOH=96.48%, Hx=85.78%. 57,697 total mi, 12768 mi on new battery. 244 L2 and 11 L3 on new battery. 1118 total L2,125 total L3. Cool weather favors the battery and degradation is minimal. March and April will likely show the same effects. The real tests will be July, August, and September. If the battery survives the summer with minimal losses then perhaps Nissan has indeed fixed the problem. At this point I have 8 1/2 months on the new battery and It is performing slightly better than the original battery over the same time period. Unfortunately the two batteries are 180 degrees out of sync in regards to the seasons so the comparison isn't exact.

I'm at 41k mi (66k km) on my 2017 S in Colorado, zero bars down, haven't done the recall yet. It sounds like it's extremely rare for a 30kWh pack to go this far without losing bars pre-recall?

Your climate has a lot to do with it. I would guess that you are a little unusual but without a Leafspy readout it's hard to tell. That first bar doesn't drop until SOH hits 84% or thereabouts. Keep in mind that this battery does just fine in Europe as well. Also that's a lot of miles on a '17 and frequent use seems to be good for the battery.

Will a pre-recall reading mean anything? I definitely agree with your assertion that frequent use seems to help. Our summers are warm but it does spend the whole winter outside at altitude.

Here is my experience with the update:

March 2018 before update:
Ahr 73.27 SOH 92.19 Hx 86.09

March 2018 after update:
76.98. 96.86. 86.81

Two weeks after update:
77.22. 97.16. 87.39

Dec 12 2018:
76.59. 96.36. 85.81

March 8 2019:
77.05 96.94 86.96

The most recent reading was after 3 100% charges, which seems to help a bit. Overall I'm not seeing much degradation, although I've only put 6100 miles on the car.

A pre-recall reading will at least show where you were. Better would be a current reading from Leafspy to see where you are now and how long it might be before you lose that first bar. If you haven't had the recall done yet, I'd suggest you schedule it soon and take readings from before and after.

No. I was over 98% at 29,413 miles on mine so very unlikely I would have been close to being ½ a bar down by time time I hit your mileage level.

Don't spend a lot of time at high SOC and you will be fine. My advantage was driving 200 miles a day but usually left each morning at 40-75% SOC. I was stopping to charge 2-3 times a day which actually worked well with my work schedule as I used the opportunity to get work done that I would have had to do when I got home anyway and billed the time to my employer so not only was I charging for free, I was getting paid to do it! :)
