This would strongly alter my plans if I were to develop an OSS Discord alternative. Chromium originally looked like a better core to start with largely due to its mature screen capture API. WebRTC is the other big thing, but there are other ways to do that. Native desktop apps (i.e., not browser based) are beginning to look much more compelling to me now.
