I’ve been around open source for 20+ years and can tell you right now that it don’t work that way. An issue tracker and a wiki is not a community.
Most older open source communities were built on irl connections and irc, with some mailing lists thrown in. Hell, we even funded conferences just around the software, not to sell a product but just because it’s good for everyone to be talking to each other.
The issue tracker tracks the status of things, the wiki is generally user focused. It’s not where development happens or thinks get built.
