I guess the question is what do you mean by “hand over to community”?
The project is all there on Github. If someone from the community wants to pick it up, I don’t think there’s anything stopping that. Snooze Tabs in particular was built in a way that it doesn’t need any special access or permissions from Mozilla, so it’s really just a normal web extension.
The folks who were working on it (including Blake and I and others) have moved onto other things. So, we won’t have time to lead or organize a community effort. There’s an open opportunity for someone who feels strongly about the project.
As for the specific “Snooze Tabs” add-on released on addons.mozilla.org - I suppose we could add folks from the community as owners to hand it off. But, I’d say that recent examples of that sort of thing blowing up into a big problem at places like NPM leaves us very reticent to turn over the keys unless someone steps up in a reliably trustworthy way.
Easiest path forward for a community effort might be to take the source and run with it under a different name. I think anyone’s welcome to do that today.
