This method is only available on newer versions. The first available version of the method is shown here.

amount_constrained(dependency) private

returns an integer in (-infty, 0] a number closer to 0 means the dependency is less constraining

dependencies w/ 0 or 1 possibilities (ignoring version requirements) are given very negative values, so they always sort first, before dependencies that are unconstrained
