A number of people package kconfig as a library that is then used
in various projects outside of the Linux kernel. Removing this
function breaks the library ABI and potentially such project. For
example, I call conf_set_all_new_symbols() from my libbuild2-kconfig
build system module[1].

I know you don't care much for such out-of-kernel usage, still, this
(and the previous commit) feels like superficial reshuffling of code
and perhaps it's worth not breaking things unless there is something
substantial to gain?
