Summary

• This work is behind a feature toggle (flipper): NO

This PR makes the following changes:

• Only send log message about considering removing features if there are any features to consider removing.
• Log when a feature is added. This will hopefully help us figure out what is adding features and where outdated features.yml live.
• Add an extra log in the rescue just to see if we've been hitting errors.
