This will be a huge help for teams of larger developers who use Github.

It's really easy for a branch to "look okay" at the unit level (generally covered by the commit status API) and then completely fail at the integration level.

Enabling quick reverts of bad code encourages people to make the "right fix" rather than trying to hotfix issues in an integration environment (which blocks the rest of the team and prevents other features from going out).
