This series was always funded with creative accounting, and was one of the reasons Bob Iger was able to get the board to jettison Bob Chapek.
The first season of the The Mysterious Benedict Society was paid for out of Hulu funds and moved to D+. Then Chapek moved the series to The Disney Channel to move the second season budget from the
Disney+ ledger to the Disney Channel ledger. Chapek did this with a few shows and movies, premiering them on Disney Channel, ABC, Hulu or wherever, as he tried to hide the true skyrocketing $30B in production costs of Disney+ from stockholders.
Now, all steaming services are cutting production costs to try and become profitable, and a new season of a D+ original that was previously never "officially" paid for by D+ is low-hanging fruit.
