Several (most? all?) scriptlet guidelines in[ http://fedoraproject.org/wiki/Packaging:ScriptletSnippet]s are not checked, including:
- Run update-mime-database when appropriate
- Run gtk-update-icon-cache when appropriate
- Run update-desktop-database when apprpriate.
- Run texinfo as required.
- Run gio-querymodules as required
- Run /usr/bin/gtk-query-immodules-3.0-%{__isa_bits} as required
- Run /usr/bin/gdk-pixbuf-query-loaders-%{__isa_bits as required
- Update gsettings-schemas as required.
- Run GConf macros as required

All of these can be partly automated and only become active if they really are required if certain file(s) are being installed by apackage
