Some people would like the feature where they are notified that the job is finished but don’t want to allow it to connect to the manufacturer. That would be possible if you could get one that uses Thread over Matter.
Most people either don’t care about the feature or don’t care about their privacy so it’s a real niche market.

I don’t need it either but the home automation guys often want to do things that I don’t understand and detecting when an appliance has finished its job is one of them.
