Title: provide override points for better plugin support

This pull request makes no functional changes but just provides a little more flexible extension points.

A common pattern seems to be that some pull requests should be refactored as plugins. To do this, it would be ideal to override as little unnecessary code as possible.

examples are:
- https://github.com/documentcloud/backbone/pull/668
- TODO find url for history tracker pull request from kpdecker
