While I certainly would prefer the non-fallback behavior for init as
well, standard kernel practice has typically been to use "default y" for
previously built-in features that become configurable.  And I'd
certainly prefer a compile-time configuration option like this (even
with default y) over a "strictinit" kernel command-line option.
