You are missing my point here i think - giving nodes a tag based on the 
vague assumption that for the majority of them this will be correct is 
inconsistent with the idea of a responsible import.  There is no 
information in this and you cannot determine for a node in the database 
afterwards if its tag has been diligently determined from reliable 
information or if it is just the automatic default.  As a result even 
the hard work of those doing actual verification on the data is 
devalued since a place=hamlet does not tell if it has been verified 
against images/local knowledge or if it has just been pushed as it is 
into the database.

If you want to responsibly perform this import and appreciate the work 
of those participating in it you should convert the data with 
reasonable defaults that do not imply any knowledge of the places you 
do not have (like place=unknown) and clearly instruct those doing the 
import to only change this after individual assessment using reliable 
information from other sources.  That way you can later assume for a 
node tagged place=hamlet that this has been verified (unless it has 
been uploaded as part of a changeset containing 1000 nodes all tagged 
place=hamlet in which case the mapper involved has probably taken the 
shortcut... ;-)
