Keep in mind that it would be conceivable to ship an 8.0.x release which
replaces ARC with another algorithm. That would be a somewhat
non-trivial change, but there's no reason we need to wait for a major
release (i.e. 8.1 or 8.2) to replace ARC.

I agree with Tom -- this shouldn't be an impediment to releasing 8.0,
but it definitely warrants attention in the future.
