Yes, I admit defeat in the attempt to fix osmi and Josm validator errors in the area. Almost every way that joins another use area has duplicated ways. There appears to be no attempt to use relations to reduce duplicated ways. 
As I dug myself deeper in to the mire, I ended up with close to a 100 conflicts to fix. Eventually I have to cut my losses and run.
I was intending to return to the area and remap everything after having a rest day.
I expect you want the area to remain untouched by me so I have reverted the changeset and resolved the resulting conflicts in favour of others.
Thanks for helping sort this out.
I will let you guys look after this area.
