This update has broken rsyslog-8.94.0-57 on RHEL7 for me. With the following in /etc/rsyslog.conf:

# This file is managed by Puppet.  No configuration is placed here
# all configuration is under the rsyslog.d directory

include(file="/etc/rsyslog.d/*.conf" mode="optional")

and no /etc/rsyslog.d files, I get the error:

RHEL8 with rsyslog-8.2102.0-15.el8_10.1.x86_64 doesn't seem to have this problem.

No logging happens

The issue is that the include() object isn't supported until rsyslog 8.33.0 while the pesudo-latest version of rsyslog on RHEL7 is about 8.24.
