I spent about 20 minutes reading the code. Yes, for inexperienced
developers it can take 3x longer, but still, much longer time was
spent on writing that code to begin with. So, the headers are a part
of the evolution of the code. And now it's pure technical debt with no
excuses to not fulfill.

TL;DR: It's (rightfully) assumed that the developer *knows* their code.

There is a Google project coming from Clang people or so, but I have
no idea of the state of affairs.
