As a user of dep, glide, godep and avid reader of vgo technical docs I favor vgo's solution. I've been a professional Go developer a few years now.
The notion that this committee speaks for the community seems a weak one to me and I've seen my view mirrored with many of my peers. Its good they attempted such research but it seems like confirmation bias as dep just seemed like a re-write of glide with similar fundamentals and a improved user experience. This appeal to authority by the committee to represent the Go community seems unproductive and unnecessarily divisive/misleading.
I wasn't thrilled when I saw become Sam elected to lead the implementation of the "official experiment" because I wasn't a fan of Glide at all. There was no community vote to oversee this, just one maintainer of one flavor of go pkg management was declared the expert and just re-wrote the existing Glide solution with some lesson's learned. Many other maintainers (experts) of other go pkg management solutions favor vgo.
I've navigated many thorny dependency problems in Go before and never have I ever been convinced that the solution was NP complete version constraints. MVS, good tooling, and finally SIV is enough to make this miles better then previous attempts in this space. Also hooray for GOPATH elimination and project based workflows I've always loved GB by Dave Cheney.
