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. :)
