I'm planning to work on that with Ronald. We'd love to have your help.

I'd been assuming you would drive that work as part of completing what

I'll have to look at the review again but my concern was things like
having a logger removed from the configuration file, but not removed
from the "live" configuration, so that messages end up going multiple
places. For example, suppose I configure a file logger, then change to
use syslog. I don't want messages going to the file any more. Similarly,
if I start out logging with the default human-readable format, and then
change to JSON, I don't want my file to contain both.
