I don't think this is reasonable as there are
several uses like:

default y
default n if <foo>

For instance:

arch/alpha/Kconfig-config ALPHA_WTINT
arch/alpha/Kconfig- bool "Use WTINT" if ALPHA_SRM || ALPHA_GENERIC
arch/alpha/Kconfig- default y if ALPHA_QEMU
arch/alpha/Kconfig: default n if ALPHA_EV5 || ALPHA_EV56 || (ALPHA_EV4 && !ALPHA_LCA)
arch/alpha/Kconfig: default n if !ALPHA_SRM && !ALPHA_GENERIC
