Maybe we could create an "openbox standalone" entry in the manual or maybe only in discourse, some people want it. We put a big disclamer hat we don't use it but we add the things add appear, for example, we could put this to make background refresh https://forum.siduction.org/index.php?topic=7693.0
I think, honestly, it's a bit out of scope. It's a nice extra, but it's not something we should make appear like we're actively supporting. In much the same way, people might want to have information on kdialog. It's extremely useful. But I wouldn't want it included in Lubuntu (you can install whatever you want and there's not enough people that need it) and I wouldn't write a bunch of documentation on it. I might suggest it to people, though. There is plenty of documentation out there about how to use Openbox.
