I thought EXPERT was the best way to manage the visibility of expert
options, but probably not, since it's prone to silent default changing. I
think it would be safer if the kconfig language had more support for this
visibility control. Maybe we need another miscellaneous option, like
'option visibility=<level>', level = {low, normal, high, experimental}.
low means practically grayed out (hopefully allowing the eye of the user
to effectively not see it), normal would be a noop, high makes it stand
out, and experimental would be like high, except also throw a canned
sentence in that says it's not ready for production. (This additional
focus on EXPERIMENTAL was inspired by your comments on it possibly
deserving a special color or something.) Of course, additional or
different levels could be conceived of, but in general I think we need
better ways to supply hints to kconfig frontends about visibility.
Something that can't get tangled up with default values.
