Comment # 1 on bug 911245 from Marius Tomaschewski

We will update BaseSystem to most recent version as soon as the time permits,
but not enable builds for 13.2 in BaseSystem -- it is not a backport but a
factory devel project:

"Base:System Factory Devel Project

This is the Base:System devel project. Its main purpose is to serve as
development project for packages around the topic of the system base in the
openSUSE:Factory distribution. If you want to participate you can contact us
individually or use our mailinglist opensuse-factory@opensuse.org. Please
report bugs to the respective bugowners as set.

Warning: This is not a backports project! Installing the packages here on an
old distribution may cause severe breakage!

DO NOT ENABLE BUILDING FOR OLD DISTROS!"

I've a home:mtomaschewski:syslog project building the Base:System/*syslog*
for old distros, but not everybody cares about older versions than factory
and the packages often do not build.

Further, what you're requesting is basically what the Tumbleweed rolloing
release is providing:

https://en.opensuse.org/Portal:Tumbleweed

Tumbleweed is based on Factory, that is as soon as Base:System/rsyslog gets
update to 8.6.0 + submit to factory is tested, you'll get it on Tumbleweed.
