OpenSSH 8.7 client ForkAfterAuthentication and StdinNull

I read that OpenSSH 7.8 has been released and that the client has added configuration directives for ssh_config(5) which are the equivalent of the -n and -f options

Quote:

- ssh(1): add a ForkAfterAuthentication ssh_config(5) counterpart to the ssh(1) -f flag. GHPR#231 - ssh(1): add a StdinNull directive to ssh_config(5) that allows the config file to do the same thing as -n does on the ssh(1) command-line. GHPR#231

This means that full shortcuts can be put in ~/.ssh/config for making tunnels and launching remote applications.
