Linking to a Carthage xcframework from a Swift Package

In the latest Swift 5.5 and Xcode 13.2.1, is there a way yet to import an xcframework from a path like ../../Carthage/Build/_____.xcframework into a local Swift package?

I tried using .binaryTarget but it doesn't work since the path is outside the package's directory.

Currently we're having to use the nasty workaround described here but it results in compiler warnings in literally every framework that links to the Swift package because the linker settings get duplicated to everything that links to the Swift package.

I guess not. Will make a pitch instead.
