Deep immutability is not a natural cryptographic
property.  I don't think we should synthesize
unnatural properties unless there is a clear use case,
*and* there has been consideration of this use case to
ask whether it arises from going about things in the
wrong way to start with.

If one sets to synthesizing nice, but unnatural
properties, one is apt wind up with the Xanadu disease.
