IMO some simple (not easy, but simple) solutions would go a long way here. - Support name spacing - Support specifying non-crates.io server (docket does this)

IMO some simple (not easy, but simple) solutions would go a long way here. - Support name spacing - Support specifying non-crates.io server (docket does this) - Throw warnings when the Git tag (if applicable) contents do not match the Cargo upload. Rate limit package owners so they are encouraged to set their tags right the first time and not move around RE: compile time execution. This is a harder problem, common to any binary file distribution.
