I can see that high level overviews of complex systems are useful to get some insights, but in the same way I have the feeling that this mentality of high level, abstract organization is the root of the problem. If you have a complex system and simplify the components into abstractions, you will repeatedly run into difficulties because you've actively ignored the dirty bits. It's an top down approach that tries to tackle all issues, but an bottom up approach could even eradicate myriads of issues.
