All the settings in InitialiseSettings.php have been moved to VariantSettings.php with
rOMWCfea69395e38699e46a5a82ff1e5884c21cf48e5d , leaving no actual settings in the former file. Apparently this is part of T223602??
Is this a permanent thing? Because it renders useless a shit-ton of existing links and verbal references to, say, https://noc.wikimedia.org/conf/InitialiseSettings.php and https://noc.wikimedia.org/conf/InitialiseSettings.php.txt (e.g., "this is because this wiki has variable X set to value Y in InitialiseSettings.php" or "to get this behavior, you need to request change C be made to InitialiseSettings.php").
