There is an interesting initiative running within the Godot Community about 3rd party SDK integrations.
I think it would be good for the C3 community to watch how well this model works, and if it looks promising, consider a similar model. The main benefit is gathering the repos together in one space and having a FOSS ethos across them. In this way, the community can be more aware of where other help might be needed if a 3rd party cannot maintain a repo, the community can potentially step in with PRs, etc.
For example, in my case, Greengrinds or the Steamworks Plus addon for webview2/Linux CEF would be good candidates (including porting to SDK V2).
The C3 addon browser is a gathering point because they might not all be supported by FOSS GitHub repos, and the repo side is more disparate.
Here's the discussion regarding this from Godot:
After extensive discussions with the community and various vendors, the Godot Foundation has decided to maintain its stance on not directly developing SDKs. However, recognizing the need for a more organized approach, the Foundation has established an official centralized GitHub organization for hosting SDK integrations, thereby encouraging community contributions.
This organization eases the burden on developers who create their own SDK bindings, as they will now be able to accept contributions without bearing the sole responsibility for maintaining the integration. It also provides a clear and official platform for companies that wish to donate their SDK integrations, offering a centralized location for these contributions.
