UTC1111 - discussion around reviews

  • The “Quick Review” channel is actually working quite well
  • A discussion on PR reviews
    • For subsystems where there are multiple subsystem maintainers you can get reviews relatively easily
    • For other things it’s great to get reviews
      • Eg. PPP PR didn’t get review for days and days
    • If there’s only one maintainer we need people to step up and have a look
    • Please review more!
