I would uninstall the screensaver so fast if I saw a nag screen. Wtf it's a screensaver, what does it matter? I'll use a version that's 50 years old if I want to.
Because the dev gets a huge number of bug reports for bugs that were resolved 5 versions ago.
They actually asked debian to stop shipping the screensaver, because they were getting tired of saying "this is already fixed, debian is just not going to ship the fix for another year". Debian didn't want to stop, so the dev added the nag screen, because it was the only way to stop the flood of bug reports for things that were already fixed.
The "install lib-blah-blah-blah" bit doesn't bother me 'cause whenever I need to make something work, I just copy and paste the "sudo apt install ..." commands straight from the internet :)
