It would be beneficial to open up testing branches, Alpha - Beta - Stable and of coarse Alpha and beta are install at own risk / not production ready / may still have bugs. from my previous post in New Roadmap
DA and other panels have these, may also speed up the release times for features the panel desperately need like catchall email, wildcard options for blocking, and improved usage stats and the list goes on.
These channels are helpful for real world testing to filter out any bugs that can be reported and test compatibility with specific environments.
Developers of apps for enhance will benefit ahead of time rather than having to wait for a full release to explore what they need to update in their code.
Hosting providers / Web designers that host customer sites also benefit as well to test new versions and what to expect on upgrading to a newer release.
These are only a couple of the off of my head.
