This is just a deficiency in the tools. The correct answer is to fix the
damn tools, not invent this silly 'select' facility which means much the
same thing as 'depends on' but is implemented differently.

As long ago as the mid-1990s, the Nemesis research OS was using a tcl
xconfig tool based on the Linux one, but which would show you the
dependencies for an option that was disabled, so you could enable them
where you needed to. Rather than just hiding the option completely.
