Thanks for the PR. Could you clarify please how is this supposed to work if our Linux users want a static library? Last time I talked to SwiftPM folks, their opinion was that this should be controlled on library consumer side, not library vendor side, otherwise consumers lose all flexibility.

With no updates from the OP I'm closing this as stale.
