[00:38:26] <Krinkle>	 I noticed today that we emit a `X-Response-Substitute` header (in addition to shorten max-age) in MediaWiki.php. That header doesnt' appear used anywhere, but what's funny is that in duckduckgo it has a singular search results: https://webtechsurvey.com/response-header/x-response-substitute
[00:38:48] <Krinkle>	 that page is bascially an overview of random wikis in the world that are broken, i.e. have a disabled message cache at runtime 
[06:12:31] <TimStarling>	 just for debugging
[17:08:49] <MatmaRex>	 is anyone around who could approve the patch from https://phabricator.wikimedia.org/T264765#9137884 if i submitted it to gerrit now? (per sbassett's suggestion on the task)
