I think we should more clearly separate the contents of the manifest and 
the version pins file.
I don't like to have two competing ways to do the same thing.

The manifest file (`Packages.swift`) should contain all required 
dependencies while the pins file should contain specific versions.

If there the dependency has no released version yet that is fine!
But instead of hard-coding some version into the manifest, we should 
allow to specify dependencies without any version requirement.
The concrete branch/version specification should always be stored in the 
`Package.pins` file.
This way, we also don't have any problem with conflicting branch 
specifications.

yes.
Bootstrapping and the ability to work with unreleased dependencies are 
important.

no.
I'd like to keep the clear separation between `Package.swift` and 
`Package.pins`.

Quick Reading.
