A few codes have been retained, for officer safety.
Some of that could work, especially if there's department policy to call the officer before giving information. There are other more effective ways of conveying duress, though. I'm not going to go into the details, but sometimes it's more of how something is said than the content of what is said.

Particularly relevant to this discussion is making the radios do what they can do on a regular basis. If you need to use a function that you have only seen months ago in training in the heat of a major incident, then either your disaster communications plan needs revision to remove unfamiliar procedures, or (more likely) your daily operational procedures need modification. (Or maybe your radios need to be set up differently.)
This was my entire argument during the "gateway" fad. I had consultants who easily made three times what I did swoop into my job to tell me all my region's problems would be solved by going out and buying a matrix box and plugging this frequency into that frequency and so on. In 2004, I was on a National Guard exercise where they trucked in vendors, outside agencies (from half-way across the country), and state and local assets. Nobody was in charge, it was a "y'all come!" event. So, the "bookmobiles" (my pet term for fancy command posts) all came in and parked. At 1000 hrs, the exercise commenced and everybody turned on what they had. The ping-ponging between frequencies boggled the mind! Someone keyed up on ICALL and brought up ITAC 2, ITAC3, EVERY SINGLE ONE OF THE VHF INTEROPERABILITY FREQUENCIES(!!!!!), two or three UHF ones, a bunch of FRS channels, and got some Nextel beeps thrown in. It ping-ponged back and forth for minutes. People were dumbfounded and speechless. It became the dictionary definition of Charlie Foxtrot.
(Eleven years later, I still don't know if this was in fact the objective of the exercise and if we were all set up, or if there was no direction because there was an assumption that everyone knew what they were doing.)
To add to my disdain for these things, the local fire chiefs each bought them so that they would not have to change VHF channels. In most cases, the frequencies were so close to each other that they desensed the other radio (and it was all VHF... just change the darned channel knob!). In other cases, one transmission went out over (and tied up) several other talkpaths that were used for other zones of the operation.
Point is that an acute incident is no time to find out that the expensive enhancement device destroys communication better than it facilitates it because it only comes out of the box every other year.
Since then, the COM-L program has come out, and the tactical interoperability plan vests delegated authority of the IC in the COM-L to establish a plan and, if need be, order a resource to be shut off. They also migrated to a different type of radio system.
Still, if no one trains on it, it's just not going to get used. If someone pulls it out of the box right there, it could hurt more than help.
