I feel it´s important to have the possibility to control access to pages in different languages. When you create a new multi language variation page it should be possible to assign team or users to each individual page. Or to ALL pages created in a specific language.
For example:
Start page - Global (Only Global editors have access)
-- Start page English (Only a specific England team or user should have access)
-- Start page German
(Only a specific German team or user should have access)
-- Start page Spanish (Only a specific Spanish team or user should have access)
Or if set globaly, so the spanish Team should always but only have access to all language pages created in spanish.
