Yeah, the signals they get will improve things over time. You can do a lot of heavy lifting with embedding models nowadays, get "satisfaction" signals from chats, and adjust your router based on those. It will be weird at first, some people will complain, but at the end of the day, you don't need imo-gold levels of thinking to write a fitness plan that most likely the user won't even follow :)

Signal gathering is likely the driver of most of the subsidised model offerings we see today.
