What version of Go are you using (go version)?

$ go version
go version go1.14 darwin/amd64

What did you do?

I installed a binary via go get at an older version than the corresponding lib that I was using. This silently removed a seemingly unrelated dependency, cause a subsequent build of my package to fail because the dependency was automatically re-added, but at the latest version.

module myproject

go 1.14

require (
  github.com/some/lib v1.1.0   // depends on github.com/other/lib v1.5.0
  github.com/other/lib v1.5.0
  ...
)

Installing an old binary via go get github.com/other/lib/cmd/binary v1.4.0 can remove the dependency on github.com/some/lib if there is no old version of some/lib that matches the v1.4.0 target.

The problem is that this removal is completely silent.

A subsequent build of myproject will automatically re-add the dependency, but at the latest version.

What did you expect to see?

I'd like a clear message indicating if seemingly unrelated dependencies are removed because no acceptable combination of versions was found.
