Yes, somewhere and at some time we are going to have to do the hard
work of analyzing whether or not hiding encryptions improves security
as a general principle (as opposed to coming up with new ways to hide
them before doing the ground work.)

Hiding something indicates that it is dangerous if revealed. It says,
basically, that encryption technology is inadequate and cannot be made
to work, the only reasonable protection is secrecy. Do we honestly
believe this? Or, worse, do we believe that security is attained by
layering anything we can think of onto the system?
