This is only because businesses are full of folks with short-sighted FOMO desperately trying to cram AI features into any product they can. AI is the new digital clock.
We've put so many layers between the engineers and customers and diluted any accountability to demonstrate positive ROI—even if it's theoretical—that we do pointless work for nobody. I'm not going to complain too much personally because all those layers make it possible for me to just pull cards and collect a paycheck but I'm surprised nobody on the business side even somewhat cares if the work they're paying for is worthwhile.
Frankly I've added some of the features of my own initiative. They were low hanging fruits and really helpful in some cases, and in others they are placeholders waiting to be better integrated or expanded depending on the users requests. Nobody forces anyone to use them or even notice them, so why not?
As I said: these features look like magic in demos, it's not because of the hype that managers want them integrated but because of genuine enthusiasm. But they require more development and maintenance effort than was apparent from the demo. Also, there's a clear discoverability problem due to the fact that an agent has basically no UI.
