Well, you may think that standards are too high, but on the flipside, yes: the expectation that you are able to deal with such a suite of tools is also out there. Maybe this reflects on the quality of the stack more than anything else - on the other hand, .Net and C# development is pitched as a reason to not have to know any of those things, too.
The problem IMO is out of the 100 or so developers I have worked with none of them fit that profile and IMO that's completely ok. Granted, I actually cover most of that except the networking side, and know a few other that come close. (Which is probably why I am standing up a continuous integration server today instead of actually coding.) But, it really just seems wasteful as the value of teams is they let people specialize.
Nobody said everyone should be a full stack developer - just that more developers should consider the benefits of becoming more proficient with the layers of the stack with which they're not competent.
