I'm wondering how the GitHub workflow interacts with Web Platform Tests repository. For example, "git-webkit upload" doesn't ask you to export changes you do in your commit to WPT tests. Though "webkit-patch upload" usually warned you about that and offered a way to export the changes. Apart from that, we used to add the WPT PR in the "See also" field in WebKit bugzilla. That one once we get a r+ in the WebKit bugzilla patch, the WPT PR was automatically approved and we could merge the PR in WPT first, and then merge the WebKit bugzilla patch later. I do wonder if there's a similar way to do that with a WebKit PR. See https://trac.webkit.org/wiki/WPTExportProcess for details. Also that page or a equivalent one in GitHub wiki should be updated accordingly.
