As I mentioned before, please keep these defaults as a -mm-only patch,
Giving them testing in -mm is fine, but defaults are already way too much
abused as is. The default rule should be to enable an option explicitly,
if it's needed, it should not be auto-enabled, because its author likes
it so much. Using a "default y" should be close to hiding the option via
CONFIG_EMBEDDED or some other option and the default should not differ
between hidden and visible state, e.g.:

config FOO
bool "foo" if BAR
default y
