Did this work in 1.13? https://golang.org/issue/35759 is probably related; see especially the TODO here <https://github.com/golang/go/blob/5a61de3fe160cc8b327ee893cd74c4d0ce9dc13d/src/cmd/go/internal/load/pkg.go#L1612-L1616> . Please file an issue <https://golang.org/issue/new> so we don't lose track of it.
