MediaWiki is bloated with many unused i18n files to the point it's getting absurd.
MediaWiki 1.25.1 (https://releases.wikimedia.org/mediawiki/1.25/mediawiki-1.25.1.tar.gz) stats:
Total size on disk: 93,188 kB
Total size of core files: 33,028 kB - 5,195 files
Total size of i18n files: 60,160 kB - 4,771 files
Breakdown of i18n files:
extensions\ ..5,962,107 kB - 2,727 files
includes\.... ...3,299,889 kB - 299 files
languages\ 50,410,010 kB - 722 files
resources\. ......133,392 kB - 204 files
skins\........... ......289,204 kB - 683 files
vendor\....... ........65,398 kB - 136 files
Is there any good reason why everyone has to download all the languages?
Most people who download the latest stable release would not need that many languages for their websites.
Please consider providing an optional English-only bundle
