According to https://wiki.ubuntu.com/AppReviews the Application Review Process is good both for upstream software developers and Ubuntu packagers. The point seems to be that the upstream developers have the advantage of getting their apps into the Software Center sooner and easier, while they help the Ubuntu package managers by preparing their application for packaging.
This seems to be a great deal. The instruction on wiki states that a developer fulfills some steps listed there, including uploading the application to a PPA, and requests review, and after some time it is reviewed, and accepted & included to Ubuntu repositories, or not accepted at all.
Although this looks like a simple, fair way to quickly add an application to the Software Center, I think I am missing something. I have noticed, that while there are some requests pending, there is no (or barely any) activity there. Everything seems as if it was frozen about 5-6 months ago, and it smells a bit abandoned.
Did I understand anything wrong, and everything is okay (maybe for example they are being reviewed only at the UDS?), or did something change? Could anyone explain me clearly, how exactly this process of reviews (and inclusion in repositories) works?
