In android-24 and newer, the user can specify multiple languages in a
priority list. Therefore, the locale chooser logic here does not need
to work so hard to find a language match. For example, if the user
wanted to see country-specific variants, they would add them to the
preference list.
With older versions of Android, the pref is only a single locale. So
chances are that someone who specified de_AT would rather see de or
de_DE than en_US. Same goes for es_AR, ar_EG, etc. This could annoy
Chinese speakers, since someone who sets zh_TW could potentially see
zh_CN, which are written pretty differently.
