We know that co.uk is not an Organizational Domain.  Asking what is the 
Organizational Domain of co.uk is an ill-posed question.

How about restricting the term to DMARC?


NEW
3.2.7.  Organizational Domain

    The Organizational Domain is typically a domain that was registered
    with a domain name registrar and complies with DMARC.  More formally,
    it is any Public Suffix Domain plus one label which publishes a DMARC
    record (see Section 5.1).  The algorithm to determine The Organizational
    Domain, if any, is found in Section 4.8.


I think this change parallels the change from PSL to tree walk, and justifies it.
