The sensitivity to prompts and response quality are related to an agent's functionality, A2A is only addressing the communication aspects between agents and not the content within.
We built similar animation part of a product few years ago. The flow was something like - when a new user signs up and users our product for the first time and creates certain artifact, the confetti animation would be displayed. Product managers loved it and they would show it off to execs as playful, refreshing, etc. But later on after UX reviews, accessibility testing, the feature was ultimately removed from the product.
It was fun to present it in demos, but it can also be annoying to users.
Over the weekend, I saw a Model S with number plate "WOZ" in Oakridge mall, San Jose. I wondered if it is him and sure enough it was him driving the car to the supercharger stations.
I was pleasantly surprised to see him driving and trying to charge the car in public locations.
