For example, if I want CONFIG_MTD_CMDLINE_PARTS=y, the system may be
smart enough to notice and automatically enable CONFIG_MTD and
CONFIG_MTD_PARTITIONS without having to carry those in the defconfig.

How do you sort out something like this:

config FOO
? ? ? ?bool "Foo"
? ? ? ?depends on (A && B) || C

Do you enable A and B, A, B and C or just C?

Bear in mind that A could be 'X86', 'M68K' or any other arch specific
symbol.

I prefer the warning method because it prompts you to investigate what's
changed and sort out the problem by ensuring that the appropriate symbols
are also selected. ?The automatic selection of dependencies method carries
the risk that it'll do the wrong thing with the above scenario.

Good point.
