Well to be fair, most people don't look at the apt's output in their scripts, they just do "apt install -y --no-install-recommends all the wonderful packages they need" and move on with "&&".
If that was the case then I wouldn't see messages that X or Y commands behavior are going to change in the future. The master branch moral panic thing comes to mind for example.
Hell, "apt" explicitly warns you not to use it in scripts, and yet everyone does.
