I think humans.txt (http://humanstxt.org/) fits more, and already exists.
Not sure why you linked that, it doesn't fit at all. They're solving completely different problems.
Google is built by a large team of engineers, designers, researchers, robots, and others in many different sites across the globe. It is updated continuously, and built with more tools and technologies than we can shake a stick at. If you'd like to help us out, see google.com/careers.
It's part of every new engineer's first day or two. It's their first shipped PR to add themselves as a human.
It should really be human.txt...
And going over my logs for the past year, I only found 6 requests for 'humans.txt' on my server.
