Translations:Schools of thought concerning integration of extensions into the core/6/en

Quim Gil [$plus-google writes], "Upgrading MediaWiki is easy, upgrading a MediaWiki site using extensions is not. Versioning extensions and aligning them with MediaWiki versions is not done consistently. And how would you know which extension version works for your slightly older MediaWiki, e.g. because you are using a LTS version?" When everything is kept in the core, these compatibility problems are not an issue.
