I've always found this to be overlooked or at least a misguided design decision. IMO would be very helpful to be able to specify a commit, tag or branch to pull down.

The Go team's solution to this problem was allowing vendored dependencies. Basically you can put the dependencies inside your project in a directory called vendor which will be used instead of whatever is in your $GOPATH/src/. This allows you to pin deps to a specific version and not need to pull deps from the internet at all.
