| Nov 28, 2023 at 17:33 | comment | added | YCor | The result on abelian groups (which I mentioned in my post, although not aware that it's stated somewhere) is very easy because every nontrivial abelian group either has a finite quotient, or else is divisible and hence has a Prüfer quotient. A similar conclusion holds for modules over any fixed PID | |
