Middlesex ceased to exist in 1965 yet many people still use it in their
postal address ... there is certainly no boundary for it on OSM :) To
add to the fun, facebook's allowed list of places miss-identifies this
area of London in the same way as the other areas that became London
Boroughs back then and this is creating a mess in Facebook's use as a
business platform.

Starting with a list of the current official designations from the ONS
database has to be the correct currently accurate information, but while
there should be a boundary associated with each entry, a simple list of
elements does not need to be overloaded with all of the way information
providing that boundary. It is a secondary relation to the base 'name'.

provides a list of the official COUNTRIES in the United Kingdom but even
that is probably inaccurate in relation to is Northern Ireland part of
the United Kingdom? ( At some time will Scottish translations also be
added? )

The Open Geography Portal provides a list of data and the basis for
checking that within OSM, but it will be easier to complete a complete
mirror of is_in: hierarchy which can be updated as changes appear in the
ONS dataset and THEN associate boundaries as appropriate.
