> the core issue was being able to have semantic import versioning, Well, the actual core issue was merely being able to use differing major releases as part of the same build, something that dep doesn't itself allow. SIV is a further tweak that's only really needed to address a common wart, namely re-exporting elements of the versioned API from one's imports without semantically-versioning them accurately in the process. What you really need is good semantic re-export versioning, which is a rather minimal subset of SIV!
