Okay, I blame a LONG day and bad memory.

  I went and found our testing notes:

macOS name        signed notarized stapled
10.9  Mavricks    OK     FAIL      FAIL
10.10 Yosemite    OK     FAIL      FAIL
10.11 El Capitan  OK     FAIL      FAIL
10.12 Sierra      OK     OK        OK
10.13 High Sierra OK     OK        OK
10.14 Mojave      OK     OK        OK
10.15 Catalina    *      OK        OK

The divider is Sierra and above: Notarized DMGs are good. El Capatan and
below, Notarized DMGs are bad.

My bad memory. Sorry to cause unnecessary concern.
