If you do not want changeLanguage('en-US') to be called, and therefore want to assert that allLanguages.includes(currentLanguage) when a language change occurs, then you cannot do so while config.load === 'languageOnly'.

If the intended behavior is for someone who prefers 'en-US' to have their language set to 'en', and to not support a whitelist that has regional locales, then you can assert something like allLanguages.includes(currentLanguage.slice(0, 2)). However, in practice, users’ accept-language headers that contain 'en-US' will most likely also include 'en' somewhere in it, as well.

Setting config.load = 'currentOnly' ensures that allLanguages will always include currentLanguage and that the only languages that we attempt to use are the ones that are on our whitelist.
