Maybe not, but I have a few comments anyway.

Perhaps we should be using some kind of attribution tag, not just
source tag to give credit to Nearmap, even though they don't
explicitly require it, the value and richness they've given to OSM
can't really be understated, especially in regional areas.

The ones I did see, the admin boundary does not even line up with the road on the nearmap imagery and to change it takes a serious amount of time.  If your mapping from nearmap or survey there is no justification for using an admin boundary as a road or joining a road to it, even for one node.

Admin boundaries are both valuable and an irritation, in the most
recent stable version of JOSM there is a filter option to hide
elements, although it would be nice if admin boundaries were hidden by
default but at least this is a start.

However don't take all the recommendations as gospel, while the
validator plugin is a useful reference it does give bad
recommendations at times, although bad recommendations should have
bugs filed about them to improve the overall accuracy.
