Known issue, I've already filed a request upstream for us to improve this together: https://github.com/microsoft/vscode-languageserver-node/issues/1057

FWIW I'm also considering turning showOnStartup false by default, so that the terminal pane isn't opened when the extension activates, and then setting this to CloseAction.Restart automatically, which especially with the startInBackground option for those that never want to see the terminal could make the extension far less noisy, but also always on and working. @SeeminglyScience thoughts?
