I don't think that would fix it, as PG would probably refuse most of the patches anyway. It's not like this forum has a lot of traffic. Patches are unlikely to get lost in the flood (12 articles in the last 24 hours, and PG last commented 18 hours ago).
The two ways to get changes into Arc, as far as I can see, are to find a bug or write some real-world code that proves your suggestion is a good one. With so little real-world code around, that means very few changes will make it.
On the other hand, the last release was all about merging News.YC so there's no surprise that it lacks new features. Who knows, perhaps the next one will incorporate half the stuff from Anarki? We have very few data points from which to draw a conclusion.
