As Steven says, the NEC is effectively a regulation since most states adopt it by reference (like the building code). If you want you could view my post as objecting to states adopting the 2014 and 2017 NEC without consideration of the effect on resiliency, instead of to the drafters of the NEC failing to consider this aspect? (I would prefer to have seen both.)
The instinct to always want to fight problems by adding more regulation leads to stagnation...
In this case I’m proposing adding a condition to a subsidy, which I think is an importantly less restrictive approach than a blanket regulation. People always have the escape hatch of skipping the subsidy if it’s overall too burdensome.
NEC 2020 brought more changes. The six simple sentences from 2014 have grown to a full page. Most of the addition is simply clarification of the requirements added in 2017. Since many states didn’t enforce the module level shutdown from 2017-2019, most people refer to 2020 as the release year that module level shutdown was added.
That does sound to me like some states decided it makes sense to not implement a part of the rules in 2017 because they considered the rules too burdensome/wanted to give companies more time.
While there is a 2020 edition of the NEC, California — along with 23 other states — is still using the 2017 NEC. If you want to check out where we’re at, and what other states are doing, you can look at this color-coded map. It’s published by the National Fire Protection Association (NFPA), the same organization that issues each edition of the NEC.
But, wait. Doesn’t the state have a more current electrical code? Yes, but the 2019 California Electrical Code (California Code of Regulations, Title 24, Part 3) is based on the 2017 NEC.
In fact, we’re probably sticking to the 2017 NEC for a while. We didn’t vote to adopt this code until January 2019. The codes weren’t published by the state until July 2019. Then, the state observed a six-month statutorily required waiting period, which means the 2017 NEC didn’t technically get enforced until January 2020.
Thanks! It seems like part of my beef is with Massachusetts being very eager to stay on the most current code. It looks like the 2020 NEC was adopted 12/27/2019, and the 2017 NEC 1/1/2017.
I hadn’t realized how atypically fast MA is doing this. MA was the only state on the 2017 NEC from January until June; CO adopted in June, ID, ND, SD, MN, WY, and WA in July, OR and VT in October, and ME in November. Everyone else not until 2018 or later (or still hasn’t).

One of the links in the OP says:

https://www.renewableenergyworld.com/solar/evaluating-the-case-for-module-level-shutdown/ is an interesting article arguing that the rules that require the expensive module-level shutdown are essentially security theater.
I wonder whether this means that they added explicit exceptions, or that they just didn’t adopt the new revision immediately?
https://up.codes/viewer/california/ca-electric-code-2022 seems to be the Californian version. In it they seem to have “adopt/adopt with amendment/adopt expect”
