To expand a little on the topic, there are multiple abstraction layers required to make the new resolver useful as a separate package.
ResolveLib (mentioned in Paul’s message) is an dependency resolver implementation in abstract, entirely divorced of Python packaging. While it can be used by other tools, the implementer would need to provide the necessary parts to “teach” it how understand Python packages. The ongoing pip resolver work is exactly that, to integrate ResolveLib into pip by wiring it onto pip’s internal representation of Python packages. This is unfortunately not really reusable for other tools, since pip’s current model on Python packages is too deeply entangled into various parts of the code base. Some extra work is needed to make ResolveLib really useful as a reusable Python dependency resolver for other projects. One way would be to implement a wrapper library to provide the same Python package semantics to ResolveLib, but with more reusable models such as pypa/packaging, importlib-metadata, etc. The current pip resolver work would be able to offer much knowledge on dealing with various hairy problems, but the code written for pip wouldn’t be directly reusable.
