I think I narrowed it down to this call:

# get_session will return a value if a session is read,
# if not it will return false and a new session has been created.
# The IP address will be counted for robot_resolution

if(! get_session($seed) and ! $::Instance->{ExternalCookie}) {
	retire_id($sessionid);
	last RESOLVEID;
}

Let's see which changes got applied to the session code between 5.6.3
and 5.7.6.
