GNOME cares about nothing that doesn't fit precisely into their "vision". This could turn out well! But it doesn't change the situation for any external contributors, or anyone who wants functionality changed in a way that the GNOMEr's that be don't agree with.
If you've got some code to contribute to that, ping the developers on IRC. Adding more comments to that issue isn't helpful. These issues aren't suffering from a lack of comments, they're missing someone to step up and do the work. The original comment was that they were hostile to this, which isn't true.
They have a history of finite resources and inability to resolve issues in a timely fashion. They ought to set goals and raise money. People really need to commit their money if they want nice things.
