Probably they still working because they have not received yet their shut down and stay home notices from the CBP

I flew LHR-ORD-SFO on Oct 1 and they were working at ORD. Also, it was so fast that I was able to get to my departing terminal in time to go to the Admirals Club for a shower and change of clothes before my connection ( door open to outside customs in about 10 minutes) which was really nice on a relatively short connection at ORD.
