One aspect of the tool exhibited in this document that I found interesting is that the design and user experience is not concentrated on a "local root to develop a new package" workflow, but "local root to develop a set of related packages together" workflow : multi-package. There is a conceptual difference between the "local packages" in this set and the "external packages" that are expected to remain stable during development (in general).
To my knowledge there is no such established multi-package concept in related OCaml tooling these days, and there are cases where we don't do very well on this workflow. For example, Thomas Gazagnaire and Jérémie Dimino have ocamlbuild plugins to rebuild the project when ocamlfind dependencies changed that are very important in this workflow, but currently not part of the default tool ( https://github.com/ocaml/ocamlbuild/issues/91 ). It mostly affect aspects of the user experience that are outside of opam's domain, but I think it may still be a relevant distinction for opam.
