I still like this idea and think it should be done, and that you all crowd-sourcing ways to tackle each other's biggest dev problems has a lot of value.
Especially now with Aurora coming up for a lot of people, as they're wondering what customizations they could / should build, this seems timely. Also wondering if our Product folks would like to get involved. I will find out!
Let me get back to you by next week on it. Regardless, if we can't make it something more formal, maybe we could devote one of our upcoming Titan / Core roundtables to trying it? Just tossing ideas out.
