You might indeed. And I would find that commentary just as irrelevant
and unhelpful.

How's this for a definition:

"The behaviour for unsettable (or unclearable) options shall be exactly
like it already is if you put them in all*.config, or if you manually
edit the .config file and run 'make oldconfig', as people have been
doing for years. There is nothing new to see here."

[dwmw2@i7 linux-2.6]$ make CONFIG_WIRELESS_EXT=y allnoconfig
scripts/kconfig/conf --allnoconfig Kconfig
#
# Could not set CONFIG_WIRELESS_EXT=y; perhaps it has unmet dependencies?
#
#
# configuration written to .config
