Post #1457316

The #SwiftLang compiler recently got support for control over which warnings get escalated to errors (or not). It also groups warnings and provides more user-facing documentation on what those warnings *mean*. However, we have about 350 warnings that haven't yet been assigned groups and documented, so the actual benefit of this feature is pretty small right now. If you're interested in helping triage these warnings and/or writing documentation for them, we'd love your help in improving the experience for Swift users everywhere. There's more information in this issue: https://github.com/swiftlang/swift/issues/79648
