I can confirm that, on OpenSky since about April 1st (give or take a week or two).

The only thing still heard on their legacy system is fire toneouts for each of the stations, plus voice traffic for Bloomfield Village fire monitors. I'm guessing the receivers in the stations are still being used, just to activate the alert systems (klaxon, lights, etc), while the voice announcement goes over the FD dispatch talkgroup.
