Actually, while it would need to be extended to other platforms, on 
ar71xx that is exactly what Minimal does.  In fact, assuming your on the 
first run of menuconfig (i.e. the only time defaults work, due to the 
way KConfig works; this is also a problem for ALL_KMODS and ALL (that 
de-selecting all kmods and for de-selecting all packages), if you 
deselect Default, all the items selected will become unselected.

It is not possible with KConfig to have an *existing* .config and have 
an option that causes deselection of selected items, that does not also 
force deselection without the option to override (e.g. depends on 
!MINIMAL won't work because it would force the item to off without 
option to override).

If you have some clever way to avoid this problem, I'd love to hear it, 
because I don't know how to do it in KConfig.  I don't see how to allow 
an *overridable* deselection of *all* items, unless perhaps one could 
introduce a new submenu that is a choice section (I'd have to test to 
see if that would actually work, or if duplicate symbols would be a
