hajimehoshi@ asked:

"Currently, 'settings.language.preferred_languages' is used as the language list
at chrome://settings/languages on Chrome OS, while 'intl.accept_languages' is
used on the other platforms. (On Chrome OS, when the language list is updated,
both preferences are updated. Please see TranslatePrefs::UpdateLanguageList.)
This change means the language list won't be synced on Chrome OS except for
initializing.  Is that OK?"

I'm not sure I understand the question. Currently on Chrome OS the language list
is not synced, and this doesn't change that. So yes, the language list will get
out of date compared to Chrome desktop. But kPrefTranslateBlockedLanguages
should still sync either way.

AFAIK, currently, changing the language list at non-Chrome-OS doesn't affect
Chrome OS, but changing the language list at Chrome OS affects non-Chrome-OS.
Does this CL changes this behavior?

     // The preference is a CSV string that describes accept languages used
     // for content negotiation. To be more precise, the list will be used
     // in "Accept-Language" header in HTTP requests.
