How to change environment variables send to server

[pendulm]

ssh_config has a option SetEnv to modify environment variable before connect.

my config is something like this

defaults:
  UserKnownHostsFile: /dev/null
  StrictHostKeyChecking: no
  LogLevel: QUIET
  ControlMaster: auto
  ControlPath: ~/.ssh/controlmasters/%C.sock
  ControlPersist: 600
  SetEnv: LANG en_US.UTF-8

but it dosn't works. I found there isn't SetEnv option in pkg/config/host.go.

Is there any way to configure this?

I would like this as well, specifically for this option:
SetEnv: "TERM=xterm"

This looks to do it:
