With these recent "private road" changes, do you mean that the roads are off-limits to anyone but the owner, as well? The tag for what is usually called a "private road" on signs and so on (i.e., not town maintained) is ownership=private.

The distinction is approximately that of a "No Trespassing" / "Private Propery" sign. 

Here's the documentation on the two kinds of private-ness:

- https://wiki.openstreetmap.org/wiki/Tag:ownership=private

Thanks for your contribution, and welcome to OSM!
