So rare that I personally have never met one, neither amongst the academics that I have met who I think have made significant contributions to computer science, nor the developers I have worked alongside. Of course, my sample population may not be representative, and in any case they would be too modest to declare themselves an expert. For me, today’s world is too complex for there to be oracles.

In all honesty, I’d be extremely concerned about their mental health if they did - the sum of knowledge across the layers is simply too much for any one individual to master. However, they do have the skills to refer to sources of information about those lower layers and make use of it.

The theoretical computer scientist that designs a cryptographic system and presents its theoretical proof to show its underlying problem is hard under an adversarial model? Or the implementors of that cryptographic system? Or is it those that discover vulnerabilities in the implementation and its uses. I don’t believe one individual can accomplish all of these roles well, yet all are important.

I have met a couple of people that are able to understand the
intricacies of all of those layers, and they are mostly sane.

And when does he become an expert in his area of development, what level of depth of knowledge is required? It is not science, but simply a matter of opinion.

I wouldn’t even expect him to know all of the details of OpenSSL, Apache, and so on. I would be happy in some cases to overlook gaps in required knowledge, if he or she demonstrates the ability to learn and adapt to changing environments and circumstances. After all, what do you with the Apache guru when you switch to another web server, or the Java developer when you switch to some other language? If he or she can’t adapt, you fire him.

I would expect a Mauritius Software developer or a Mauritius sysadmin to
be able to at least understand how Heartbleed works under the hood, to
better understand the implications behind the vulnerabilty for an
organization.

A quick example: A few people were quick to talk about patching for
Heartbleed in this thread. Great. However, nobody spoke (up to now)
about the need to renew certifications as private keys might have been
leaked silently before the server was patched.
