Yup, the PSL is used by a number of browser manufacturers to scope cookies...

Yes -- the IANA root list (unfortunately) simply doesn't contain the information needed to correctly determine where a cookie can be set. The PSL helps prevent a cookie being set at e.g: .co.uk.

I am on temporary hiatus, but when not on exclusive projects, I volunteer time and experience to the initiative as it needs tighter nexus with the DNS community.  Many of you have perhaps seen me presenting it at ICANN meetings within the CCNSO tech day or other forums to help elevate awareness in the past few years.
