Setting up as you described earlier, is there a way to allow only a single program to drop core?
Of course.
The * in the limits.d file is a “domain” value you can adjust to suit:

You can also adjust the sysctl pattern path to put cores somewhere secure. That’s the normal use of absolute paths: put the cores into a dropbox directory that only root can read but anyone can write to.
Also, I should point out that my first step, removing ABRT, is a heavy-handed method. Maybe what you *actually* want to do is learn to cooperate with ABRT rather than rip it out entirely.
how about "simply" disabling and stopping it?
