[swift-build-dev] How to use the Package.pins file

I agree, and SE-0145 specifically recommends against using pinning for libraries.



> The "pins" file allows application builds to reliably produce the same resolution, time after time.


If an application requires the exact same dependency version resolution, then why not put an exact version in the manifest? What is the point, or the benefit, of using a loose version in the application's manifest plus an exact version in the "pins" file instead of just using an exact version in the manifest to begin with?
