Remove this distinction without a difference. Originally, the thought was to 1) Isolate the cross-module build infrastructure 2) Provide a signal to the driver that a dependency had swiftdeps info in it But the driver need only notice swiftmodule files as external dependencies and try to extract that information if it can to divine the signal it needs. Additionally, we can give it fingerprints as priors to let it know there might be incremental info to be had.
