HI, Hans Thompson! 
My name is Kate, and I’m a mapper on the OSM team at Lyft. 
In this changeset I didn’t add the tag ‘access=private’ for Lockheed Ave, I have removed it only for the middle segment. 
This tag was added long before my edits for most roads in this area (based on history the tag was added in 2007 by DaveHansenTiger https://pewu.github.io/osm-history/#/way/8910585) and in our practice, we try to avoid removing the tag ‘access’ from roads in the airport area without strong evidence.
Best regards!
