It is bad enough that systemd developers belittle users for the breakages they suffer from systemd, it is worse that you join this behavior. The lockup/freeze bugs from fifos/cdevs/sockets are real and systemd is the only init system affected, as the other init systems do not have functionality that would need the open() calls.
