Why do we have docs in the first place?
For test cases I think it's a crucial part, because tests many time are written
by newbies, who would like to understand all under-the-hood stuff. You imply
that they need to drop themselves into the code directly. It's very harsh to
begin with Linux kernel development, really.

So, no go for this w/o documentation being up-to-date. Or be honest to
everybody, it's sucks it needs to be removed. Then I will get your point.
