Fair enough.

On the other side, value of "make randconfig" has been reduced significantly
compared to earlier times, when patches like this tended to be accepted into
release candidates. Until a few releases ago, "make randconfig" usually passed
at least for main targets by the time a kernel was relased. With this no longer
the case, fewer and fewer people will look into nightly or per-rc build results
and provide patches. This in turn will likely reduce reliability, as real
problems are more and more hidden among all the "unreal" build errors.
In addition to that, more and more people will end up with non-buildable
configurations and have to spend time trying to figure out why exactly
a build failed.

But maybe this is all my imagination, so feel free to just ignore my ranting ;).
