Debug interface remotely accessible

Hey,

I'm using go-langserver for local Go development and noticed that it opens a TCP server on port 6060:

$ netstat -tulpn
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp6       0      0 :::6060                 :::*                    LISTEN      25420/go-langserver

Is this intended? I'm not sure what functionality this debugger provides, but it's probably best to not have it open to the network.
