Of course, yes.

To quote Austin :

"The use of efuses to make it such that only a particular device is able
to load a particular bitsream is a requirement typical of the gaming
industry (slot machines). This is a feature that we are looking at
introducing in the future (if it does not compromise the higher level of
security)."

So, seems Xilinx will also be doing this, sometime...

In Security, the more hurdles, the better.

It is, of course, only as strong as the weakest link.
