Avoid large pull requests

Tip: Avoid large pull requests. Find ways to break them up into smaller ones.

Small PRs can be:

• Easier to review. Intent is clearer and mistakes are more obvious
• Less likely to conflict with others work
• Compatible w/large new features - e.g behind a flag
• Not a panacea :)
