With parameter -W, netstat -rnW the "Use" column is back, but -W is for "Mtu". The column "Use" was removed in the r259562 and added back in the r262763.
batch change: For bugs that match the following - Status Is In progress AND - Untouched since 2018-01-01. AND - Affects Base System OR Documentation DO: Reset to open status. Note: I did a quick pass but if you are getting this email it might be worthwhile to double check to see if this bug ought to be closed.
With the new routing table there is nothing in kernel that would represent "Refs".
