If I’m understanding your question correctly the answer is “sort of.” The main community I know of is !fedibridge@lemmy.dbzer0.com which sees pretty regular activity but it’s more focused on promoting the fediverse rather than a checklist of goals. That’s the closest one to what you’re asking for that I’m aware of.
To a certain extent I think the list of goals has sort of defaulted to development related stuff. A lot of the growth across the fediverse is being driven by whatever mass exodus is happening at any given time. There’s definitely a desire to onboard more people more organically but it’s hard when people are expecting drop in replacements for the largest social networks on the planet.
There seem to be a lot of people who are looking for easier ways to introduce people to federated social media as a whole. If you search around I’m sure you’ll find an assortment of posts outlining their ideas about what makes Lemmy/the fediverse harder to use. Maybe that’s a good place to start building a more comprehensive list of what’s needed to grow more on merit and not as a last resort.
