Style Request: American Geophysical Union (new)
There will be a new AGU style after Sept. 1. It is based on APA with one exception: For references by three or more authors, citations are abbreviated using “et al.” after the first author: (Zhang et al., 2005).

Here is what the problem looks like:
Automatic in-text citation (Nicolas Flipo, Rabouille, et al., 2007; Vilmin, Flipo, Escoffier, Rocher, et al., 2016)
It should look like this: (Flipo et al., 2007; Vilmin et al., 2016)
"For references by three or more authors, abbreviate citation using “et al.” after the first author: (Zhang et al., 2005). Please note, this is a deviation from APA style (which lists all author names in works by three to five authors in the first citation in text and “et al.” in subsequent citations)."
and
""If two or more references from the same year contain the same first six or more authors, use a, b, c, and so on for the in-text citation and in the references list (e.g. Tuller et al., 2016a; Tuller et al., 2016b). This is the case even when the entire author lists are not identical. This is to avoid ambiguity in the in-text citation. See also References list, below."
We looked at the AGU CSL file (dates 5/22/18) and noticed the citation bit looks like:
<citation et-al-min="3" et-al-use-first="1" disambiguate-add-year-suffix="true" disambiguate-add-names="true" disambiguate-add-givenname="true" collapse="year" givenname-disambiguation-rule="primary-name">
I don't think all of those disambiguation rules should be set to true. We took out all of them except for the disambiguate-add-year-suffix (which is AGU's direction) and we got the expected result with our citations. I'm not sure if this is the correct place to post, but if there is a specific person we should email, I'm happy to do so. There were a bunch of people listed in the AGU CSL file, so I wasn't sure who the right person to contact was - this is the first time I've had to do this :)
Thanks for any help & feedback!

What would be the solution to that? I can post examples if it will help, but it may take a moment to generate them (they are on my colleague's computer).

If it is not possible to completely comply with the AGU referencing guidelines, how about having two official variants, one which works for 6+ identical authors and one for 2-6 common authors, and hope that not many people have both situations in one manuscript? It is working very well apart from this so far.
But if I turn them both into 2017, you should be getting
(Sasgen, Martín-Español, Horvath, Klemann, Petrie, Wouters, Horwath, Pail, Bamber, Clarke, Konrad, & Drinkwater, 2017; Sasgen, Martín-Español, Horvath, Klemann, Petrie, Wouters, Horwath, Pail, Bamber, Clarke, Konrad, Wilson, et al., 2017)
We're not going to create 2 official styles for such edge cases, no, sorry.
"For references by three or more authors, abbreviate citation using “et al.” after the first author: (Zhang et al., 2005). Please note, this is a deviation from APA style (which lists all author names in works by three to five authors in the first citation in text and “et al.” in subsequent citations)."
AGU's rule makes sense, because you have the first six authors in the bibliography in any case, so listing those in text doesn't require changing the bibliography, it just makes the in-text citation a bit more wordy.
(Smith, Meyer, Doe, Marx, Weber, et al. 2001; Smith, Meyer, Doe, Marx, Pareto, et al. 2001). That's in line with APA.
But (Smith et al. 2001a, b) if the first six authors are the same, even if the 7th one differs. That's different from APA.
