Project reactor provides an api to expose metrics from it's internal schedulers. These metrics are very useful and I can see it being beneficial to expose these by default within spring boot as this feature may be overlooked by some. One option would be to enable them by default with a feature to allow the user to disable if needed.

How do you enable them: Schedulers.enableMetrics();
