SwiftPM - Unsafe flags are disallowed in dependencies

Hi,

we are trying to add swift package manager support for gRPC, and we do need unsafe flags, but we got a build error when using unsafe flags. looks like unsafe flags are not allowed in dependencies, is that right? Is there a workaround?

When adding gRPC as a dependency directly which contains unsafe flags, the build fails. However, using gRPC as a transitive dependency via revision hash can work. But it still fails if we switch to use versions. Do you know why?

Looks like swiftPM only allows unsafe flags for local and branch-based dependencies. swift-package-manager/Workspace.swift at main · apple/swift-package-manager · GitHub
