Some users in the Illustrator community have complained about the invasiveness of the new "Print Bleed" generative AI button, which appeared a few weeks ago. The team has been working to provide a quick fix, and the Generative Print Bleed now has a preference to hide the icon (29.6.1).
I find the new feature very helpful: if you set up a Bleed for your document, Illustrator can now generate vectors to fill the Bleed area, so that you don't have to cut into your artwork.
