 Typically, PRs are merged as one commit (squash merges). It creates a simpler history than a Merge Commit. "Special circumstances" are rare, and typically mean that there are a series of cleanly separated changes that will be too hard to understand if squashed together, or for some reason we want to preserve the ability to dissect them.
