Comment 14 for bug 974480

This causes a real problem with Gtk Perl applications. There are no Perl modules to create indicators for Gtk3 (that I could find). All I could find was Gtk2::AppIndicator. You are effectively forcing Perl developers to Gtk2 rather than allowing us to move forward to Gtk3 development. This halts development of new programs that culd take advantage of the new library because you are imposing an arbitrary requirement that not all environment yet support.

Until there is a full suite of functionality for Gtk3, removing any backwards compatibility just hurts developers and users alike. Ask yourselves this: Who/what is being hurt by allowing the whitelist to exist ?
