ABC should NOT be "ON" by default.

As to whether it should be in the kernel at all, or how it interacts
with the code base, that's an implementation issue. I appreciate the
complexities, but the decision of whether to use it or not should be
made solely on whether it is recommended for widescale deployment or not.

Thanks for the update; it's worrisome that Linux's defaults are that
ephemeral, though.
