Was dropping the explicit LimitNOFILE and PID settings from the recent release intentional?

A previous configuration:

ExecStart=/usr/sbin/rsyslogd -n -i/var/run/rsyslogd.pid $SYSLOGD_OPTIONS
UMask=0066

Restart=on-failure

# Increase the default a bit in order to allow many simultaneous
# files to be monitored, we might need a lot of fds.
LimitNOFILE=16384

We're overriding with our own unit file, so the end result was only a brief outage of one of our receivers (related to the open files limit being exceeded), but it caught me off guard. Figured I'd check here to see if the set of changes were intentional.
