Thank you Rob, I enjoyed reading your post. I hope it drives more people to
do their POI imports with the Conflator.

I have a single comment about "it assumes the third party data is correct
and more up to date than any OSM data it is replacing". The third party
data does indeed need to be correct, otherwise we should not import it into
OSM. But in the profile "master_tags" property you choose a range of
attributes that override these mapped by OSM members. For example, if you
consider postcodes in OSM better than in the third party data, you don't
add the "addr:postcode" to that list.

Also, nodes and areas are almost never moved, never for the initial import.
Locations from OSM are considered to be the most precise. Of course, with
the Community Validation tool mappers can adjust some locations to match
these from a third party dataset.
