Environment variable substitution doesn't work in settings.json

[anoopknayak]

I have a vscode workspace with the workspace settings as follows:

{
  "go.toolsEnvVars": {
    "GO": "${env:GO}",
    "GOBIN": "${env:GOBIN}",
    "GONOPROXY": "${env:GONOPROXY}",
    "GOPATH": "${env:GOPATH}",
    "GOPRIVATE": "${env:GOPRIVATE}",
    "GOPROXY": "${env:GOPROXY}",
    "GOROOT": "${env:GOROOT}",
    "GOSUMDB": "${env:GOSUMDB}",
    "USE_ATHENS_GO_PROXY": "${env:USE_ATHENS_GO_PROXY}"
  },
  "go.goroot": "${env:GOROOT}"
}

direnv extension logs picks up the value correctly but the Go extension complains saying that ${env:GOROOT} is not a valid goroot.

Is direnv the first extension to start or can that be guaranteed in any way so that the environment variables are loaded before any other extension?
