That's correct for the time being.  The way we know that a copy of a file needs
self-heal is by looking at the flags on *other* copies of the file, so if
something happens to the file itself that's effectively invisible.  We've built
some of the infrastructure that will eventually be needed to support storing
CRCs along with data, because it's similar to infrastructure we need for other
things, but the feature itself is likely to remain a long way off.
