The term 'suffix' isn't really the issue -- it is the subset of 'suffixes' deemed 'public'. Quoting RFC 6265: NOTE: A "public suffix" is a domain that is controlled by a public registry, such as "com", "co.uk", and "pvt.k12.wy.us". This step is essential for preventing attacker.com from disrupting the integrity of example.com by setting a cookie with a Domain attribute of "com". Unfortunately, the set of public suffixes (also known as "registry controlled domains") changes over time. If feasible, user agents SHOULD use an up-to-date public suffix list, such as the one maintained by the Mozilla project at <http://publicsuffix.org/>. I have to admit this definition has confused me for some time (e.g., what does "public registry" mean in this context?), but ignoring this, I find it odd that a registry as important to Internet operations as the "public suffix list" is not maintained by IANA. The fact that .CW was not automatically added to the list increases the oddness factor for me.
