Fair enough I guess. I don't find this too compelling, but it may
be of interest to some.

Are the results always logged? If the DNSSEC validation status
is not recorded for posterity then it is likely futile.

The documentation should not promise any significant security
advantages to turning this on. Some users may be misled into
thinking they're enabling a security feature, rather than an
audit-trail feature. For most users leaving such explicit DNSSEC
lookups off will be a sensible default.
