OSRM uses this route when trying to route from Ball Arena, 1000, Chopper Circle, Auraria, Denver, Denver County, Colorado, 80204, United States to Denver International Airport, 8500, Peña Boulevard, Denver, Denver County, Colorado, 80249, United States (http://map.project-osrm.org/?z=14&center=39.884615%2C-104.673615&loc=39.748684%2C-105.007544&loc=39.860668%2C-104.685367&hl=en&alt=0&srv=0) This includes private roads and is NOT a legitimate route. Also made a thread about this in the osmus Slack domain (https://osmus.slack.com/archives/C029HV951/p1617747002024900).

The primary question here is: should the private road entrance be designated `access=no` and `emergency=designated`? This will require real world verification about the purpose of the private road.
