    Exactly. The point of following a code style is to make obvious patterns easy to spot and deviations stand out. That’s why code style guidelines say your priorities should be:

    1. follow whatever style the code around it uses
    2. follow project style guidelines
    3. do the technically optimal option

    3 should only be prioritized if the win is big enough, and there should probably be a comment right there explaining why the deviation was made.
