Another "low-tech" way of disabling .core file generation is to create
the core file yourself, as a symlink to /dev/null:
% ls -lFgd $HOME/*.core
lrwxr-xr-x 1 jonathan jonathan 9 Feb 16 2022
/home/jonathan/WebKitWebProcess.core@ -> /dev/null
lrwxr-xr-x 1 jonathan jonathan 9 Apr 23 2022 /home/jonathan/ctwm.core@ ->
/dev/null
lrwxr-xr-x 1 jonathan jonathan 9 Feb 16 2022 /home/jonathan/evince.core@ ->
/dev/null
lrwxr-xr-x 1 jonathan jonathan 9 Feb 16 2022 /home/jonathan/firefox.core@
-> /dev/null
lrwxr-xr-x 1 jonathan jonathan 9 Feb 16 2022 /home/jonathan/iridium.core@
-> /dev/null
lrwxr-xr-x 1 jonathan jonathan 9 Feb 16 2022 /home/jonathan/mutt.core@ ->
/dev/null
%
This is a bit ugly, but it takes effect immediately and doesn't require root.

involved is like a history book describing the booming economies of the
ante-bellum cotton states without mentioning that it was all built on
slavery." -- Phill Hallem-Baker
