That's an interesting restructuring. I wonder if perhaps they've (hopefully temporarily) reduced the number of cruise staff on the ships. Under the previous organization, half of the cruise staff team reported to the Club Host and the other half reported to the Bingo Host. Those two host positions then reported to the ACD.
What I find particularly curious about this was what I noticed in one of the audition casting notices for the Wish:
Disney Wish Casting Call Searching for Ship Wide Actors • The Disney Cruise Line Blog
"Ship Wide Actors are improvisational comedians as well as MC's, game show hosts, and more."
The rehearsals were noted as taking place in Toronto in February 2022 with performance contracts ending in October 2022, so it sounded to me like they were taking the "Club Host" non-supervisory responsibilities and moving the positions in with the mainstage performers. I don't know if that's purely because it's the launch of a new ship, or if this is going to expand across the fleet. When they start casting the roles for subsequent contracts, I may consider registering to audition.
