I don't think there are any plans to make this a pop-up. But it's still useful to move this entropy to be something that has to be actively collected: people can see which sites are collecting what information, and eventually browsers can start enforcing something like privacy budgets (https://github.com/mikewest/privacy-budget https://github.com/mikewest/privacy-budget). You can't do these with something always sent automatically.
