If a Windows instance is provisioned with SSH keys (i.e. no_ssh_keys is not true), then it would be nice if the instance had SSH access out of the box, with project and collaborator public keys added to the authorized_keys file on the Windows server.

Currently, Windows instances do not run sshd out-of-the-box. However users can easily install OpenSSH server themselves once they have RDP'ed in (https://learn.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse?tabs=gui)
