It seems that we still differ that putting them in /proc is required. I don't see a hard requirement for that as long as the vmlinu[xz] or bzImage etc. file contains the config strings, which is what the other mentioned patch does.
They are still affixed to a particular file, and they can be pulled from it whether it's the running kernel or not. Putting them in /proc wastes RAM and is undesirable, at least on small systems and most embedded platforms. However, that patch does also contain an option for putting the config entries in /proc. :)
