This is another one from chats with Mike Wannamaker. Right now dirty checking for incremental deployment compares server last mod times (timezone-adjusted) with local filesystem last mod times to determine what needs to be deployed. While this is overall more efficient than deploying everything every time, it still adds non-trivial time to the operation. An option to use only local filesystem mod files against the last successful deployment timestamp would make this considerably faster for those who can safely use that option.
