The DefaultLanguageVariant configuration option was introduced in 5b2a644 (r18754) and is used for multivariant sites.

However, it can only set for 1 variant, which means it doesn't work well with multilanguage sites.

We should introduce new DefaultLanguageVariants configuration option to replace it.

$wgDefaultLanguageVariants = [
    'sr' => 'sr-el',
    'zh' => 'zh-tw',
];

$wgDefaultLanguageVariants['sr'] => 'sr-el';

Version: 1.22.0
