I didn't find that argument very credible, particularly not the part
that assumes we know what the oldest snapshot is. I remain of the
opinion that this is going to be a large, complicated (ie buggy),
poorly performing mechanism to hypothetically someday save 4 bytes
that, even if we do save them, are just going to disappear into
alignment padding on most newer servers.
