 Replying to [comment:4 mcs]:
 > When the prefs are disabled, does the browser still parse the data sent
 in the X-ChromeLogger-Data headers? I don't think this feature raises an
 obvious security or privacy issue, but it would be bad to leave server
 logging enabled if it turns out that there is a bug in how the JSON data
 is parsed or presented.

 Good question. I added a `dump` statement to the part of the code where
 the "X-ChromeLogger-Data" header value is parsed. I was able to manually
 confirm that this code is not called except when "Server" logging is
 enabled (through the button in the devtools UI, or in the prefs). Here's
 my test code in case anyone is interested:
