That's a really great suggestion - have added that in at the end of point 

"This data should be published as an .osm file for community validation. It 
should be run against the JOSM Validator, essentially checking its 
correctness against a theoretical blank map."

Yes, I think this is very important and I included that - see mentions in
5) v.
5) vii.
6) xiii.
6) xiv.
and the addition of the JOSM Validation step noted above.

I've added in a new point 4, covering these two:

4. Post in the imports mailing list a full description of the proposed 
process, seeking consent:

Added in explicitly as part of point 3.

Agreed, and added in mention of the tagging list.

Useful suggestion. I thought just starting with a small area would be a 
sensible alpha stage, but actually within that having a single asset type 
first, and then following with the other types when that is successful, is 
a good idea.
