More importantly, the pressing need is censorship resistant contribution. Today, if a user gets banned from github, like that Bisq contributor recently, it stunts there ability to participate.
If a project gets banned it can be disruptive short term and they have to move to another centralised alternative to repeat the process.
That's not freedom technolgogy.
If collaborative contribution moves to nostr, it would be a minor irritation to switch from GitHub to a different gitserver or a few mirrors.
