RepeatedMsgReduction should be off by default

[Msd]

Maintainers explains that this option should be off :
https://www.rsyslog.com/doc/master/configuration/action/rsconf1_repeatedmsgreduction.html

> This parameter models old sysklogd legacy. Note that many people, including the rsyslog authors, consider this to be a misfeature. [...]
> - While turning this feature on can save some space in logs, most log analysis tools need to see the repeated messages, they can’t handle the “last message repeated” format.
> - This is a feature that worked decades ago when logs were small and reviewed by a human, it fails badly on high volume logs processed by tools. [...]
> This turns on repeated message reduction (not recommended):
> `$RepeatedMsgReduction on # do not log repeated messages`

So I think this option should be off by default in Ubuntu.

This option is Off in Debian 10.

Is there a reason why this is option is on on Ubuntu ?
