This is my experience too that systemd-coredump is doing something
unexpected. When I tested the patch:
https://lore.kernel.org/lkml/cover.1629655338.git.olivier@trillion01.com/

to make sure that the patch worked, sending coredumps to systemd-
coredump was making systemd-coredump, well, core dump... Not very
useful...

Sending the dumps through a pipe to anything else than systemd-coredump
was working fine.
