I've worked a little on gtk-theme-config after seeing the Debian bug for the first time (plus it's actually utterly broken with modern Gtk+3 versions) and to be honest I don't see how it could work with the way themes are set up these days with sass and resource files. (E.g. changing the selected-bg-color, which was one of the most prominent features, is practically impossible to "get right"/consistent results with multiple themes.)
So we will likely drop it from Xubuntu 18.04 and it will become deprecated. I guess Debian should drop it too, can't imagine anyone still uses it for anything (only the Gtk2 parts still work ok).

I'd be happy to file a Debian removal bug for gtk-theme-config if
that's what y'all want.
