mod_systemd and Apache 2.4

["Rose, John B" <jbrose@xxxxxxx>]

Looking around I see this in the default Apache 2.4.6 setup on Red Hat 7 ..

/etc/httpd/conf.modules.d/00-systemd.conf

I also see the LoadModule is uncommented …

LoadModule systemd_module modules/mod_systemd.so

When I go here …

http://httpd.apache.org/docs/trunk/mod/mod_systemd.html

The breadcrumb indicates that is in the version 2.5 documentation

My question is, is that module doing anything in 2.4? 

If not, then commenting out the LoadModule  seems like a good thing to do to reduce the RAM usage. Correct?

Why is it uncommented by default?

Thanks
