Ah, I use this as my main source of gender gap news, so maybe I just don't know what's going on because it's not being reported here. (I did read here about Ada Lovelace events, and I saw it mentioned in at least one media outlet, but not more than that).
But I'm confused as to why the WMF would move away from efforts to address the gender gap. I think it's great that you and others are devoting your free time and resources to this, but wouldn't it be more effective to allow someone to devote an experts full professional time to it? That person could also be a liaison to any usergroup or affiliate that gets set up, and an advocate within the WMF to allocate resources with the gender gap in mind.
One thing that's been discussed is the environmental challenge that Wikimedia projects present which particularly effect women, so why not spend some time developing sustained protected channels for collaboratively generating content to be submitted? Polished submissions are far less likely to be deleted or trashed, and it might mitigate a lot of the problems with difficult personalities. That's just spitballing, I'm sure most subscribers to this list could up with many more and better ideas for really potentially meaningful impact.
Fundamentally, the WMF has a ton of money and has dedicated a huge amount of effort and infrastructure to giving it away. Sue has publicly argued that a lot of that money isn't necessarily being well spent, so when there are such clear opportunities to address what really is a core flaw for Wikimedia projects... why not push funding, resources and brains towards them? I'd love to see a "Wikimedia Campaign" to close the gender gap that has the status of a strategic initiative. It seems particularly appropriate for something like that to form one small, lasting part of Sue's legacy as ED.
