Note that "systemd-coredump" will honour the resource limit anyway, even if the kernel ignores it as soon as a core_pattern is installed. I am pretty sure we should honour resource limits if they are set, as they are pretty OK and well-documented way how to enable and disable coredump collection, and well, putting limits on them. Note that abrtd (to my knowledge) ignores the resource limit, and will collect coredumps in anyway if if disabled with it.
