I think it is a good direction.

I think we inevitably will need to interface more with system package managers in order to do a great job of being seamless and working out of the box, and while the addition of "providers" to the Package.swift is going to have a maintenance cost, it seems sensible to go ahead and start building out this support. This design also allows the community to effective contribute a lot of the information on the package name correspondence.

The one thing I feel the proposal lacks currently is how tag versioning information in the Swift package is going to correspond to the underlying system package. My expectation is that we probably want Swift system packages to try and adopt a versioning scheme which matches that of the underlying system package.

Yes, this is a common initial pain point with using system modules, and will make it easier to understand the behavior in the context of other system package tools and standard project development environments (e.g., autoconf projects).

I think it fits well, the intention is to

Not in this form.

In-depth study.
