Let me elaborate a bit more:

- A developer is just playing with some packages in extras-devel: no Downloads page.

- A developer thinks the app is in a shape good enough to be promoted to -testing: Page created with Alpha label.

- An app makes it to extras-testing, ideally the page would be automatically updated to Beta within a week. Otherwise the change would be made manually.

- An apps makes it to Extras, ideally geta automatically updated to Stable quality. Otherwise the change is done manually.
