As someone who spends a lot of free time testing mainline -rc and -next kernels, I totally and absolutely agree - and maybe for kernel maintainers of specific kernel features and modules to check from time to time that their help text is up-to-date - obsolete documentation has caught me out more than once, and not only wasn't I knowledgeable enough about those features/modules to provide an update patch, I didn't even know where to start looking :-/
Tips like make localmodconfig are really useful, but only go so far, and the trial-and-error approach of squeezing a kernel down gets old *really* quickly. But it has to be done; if simply building a new kernel takes a lot longer with a bloated distro config, imagine how much worse this is when you encounter a bug and have to do a bisect...and all those extra new and sometimes arcane features disappearing and popping up again as you whang back and forth from one kernel version to another...
The last time I had to pare down a distro kernel for a new test setup it took me more than *two weeks* to come up with something that was minimal enough to be efficient and still worked, and even then I had delayed starting it until I had a long weekend because I knew it was going to be such a PITA.
Some of this can be put down to naivety and lack of time, but I'll bet that's the case with a lot of testers - we're not developers and are doing this in our spare hours, after all.

Like the others say, it would be great if this could somehow be available to the rest of us...possibly at kernelnewbies?
