This is not *entirely* true, it’ll just be *really* slow without it since we’ll need to download files to get their dependencies. The flip side is that It’s pretty easy for us to add it in right now for Wheels, but of course, we can’t for sdists, which I think is fine because it’s just another reason why all projects should strive to upload wheels when they can :) > > The lack of a proper resolver when doing bulk upgrades is also a much > bigger issue for pip/PyPI than it was for yum as the latter relied > heavily on repo curation to limit the chance of conflicts.
