nit: Probably need to update this comment to remove cert references

Most of the comment is in the implementation file at the use site of
IsHostnameNonUnique; I added the TODO, which was really the only thing missing
there.

+// according to the CA/Browser Forum Baseline Requirements (v1.1), they
+// represent a real risk for the deployment of new gTLDs, and thus being
+// phased out ahead of the hard deadline.
