You only want to merge these changes after there was enough time for discussion, reviewing changes, and decide that it is fully ready.

Adding a new feature
Changing how a feature work
Major refactoring
Show Pull Requests
You will chose to make a Choose Show pull request when you want to show what has been done, but otherwise you would like it to be merged automatically. You might still want to ask for review, but you essentially use it as validation and you don’t need to enter in a deep discussion.
