Good point! :-)
A better solution is to just install an AC-4R in the power supply, make
sure the Jones connector is pushed fully on (they really ARE tough to
remove when fully engaged), and get on the air!
Another answer for the connector question is to make sure that the cable
isn't "hanging" from the connector, e.g., lay it on the table, lace it
to a bundle or to the transmitter ground wire.

There's been some good suggestions on how to monitor the bias supply
and prevent damage when it goes bye bye.
but..
the first thing everyone needs to take into consideration is this.
Do you want to put the protection inside the power supply?
Or inside the rig?
the problem with a loose connector cooking the radio would not have
been solved by a circuit in the power supply.
on the other hand...
a pcb wired inside the rig must have the dimensions to fit EVERY Drake
rig.
To use such a design would require a major rewire of the power socket,
adding the new pcb, and then rewiring the rig.
WHile it's known that loosing the bias will damage the tubes (PA) is
the solution worth the effort?
