A better example of skipping a QA check would be a pair of two-way
roads that meet at a corner.  One of them is made temporarily one-way
for construction, leaving no legal way to drive both directions on the
other road.  Normally, this would be flagged as a network-connectivity
error, but if the one-way-ness of the other road is marked as being
temporary, the connectivity error can be ignored.
