Great example. Referencer is the _only_ application so far that I've been beaten up about in my family technical support role in the transition from a gnome2 to gnome3 desktop experience on Fedora.
When it went missing I given a very specifically told to get that back on the desktop and laptop systems in use. So I resurrected the necessary bits from Fedora packaging git and rebuilt it and its "longer than I really felt comfortable with" set of dependencies for in-family packages. I'm sure as hell not going to offer to maintain this for anyone outside my household.
We are evaluating replacement applications. So far, the user in question hasn't really liked the other options available. If it were a C application, I could probably seriously take a look at porting it. But the fact that it uses c++ bindings, bindings which themselves are not being ported afaik, porting it is a not starter. I'm not going to put myself on the hook for maintaining low level c++ binding as prereq to port this application. It'd be easier to nuke it from orbit and rebuild it as C or vala using the maintained bindings.
