In order to support this workflow, the pull requests are kept as small as possible on purpose so they can be reviewed easily and merged quicker. Multiple pull requests can be opened if the work to be carried is too large to fit into a single one.

" Reviewers are also developers who have tasks to do. Reviewing a pull request takes time. As a reviewer, when I see a big pull request which contains a lot of features I don't want to review it right now but later because I know I am going to spend a lot of time on this pull request.
