I was thinking incrementally ... something about UDFs only might
be quickish to do as a PoC. And is already useful, because if exposure
of a particular thing bothers you enough, you can make a UDF or P to
control it with.

But ultimately, if ALTER USER PASSWORD has sensitivity of
its parameter hardcoded in, and CREATE TABLE ACCOUNTS can declare
creditcardnumber SENSITIVE, then maybe those bits go out to the client
in the parameter Describe message, and come back in the Bind message,
without the user even necessarily thinking about it.
