That's a really great suggestion - have added that in at the end of point 
4:

"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:
https://lists.openstreetmap.org/listinfo/imports

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.
