We also do log reviews, but 99% of the time they simply complain about the volume rather than the contents.

Do you enable debug logging in production? In our setup we log at info and above by default, but then have a config setting that lets us switch to debug logging on the fly (without a service restart).

This keeps our log volume down, while letting us troubleshoot when we need it. This also gives us an isolated time of increased logging that can be specifically audited for sensitive information.
