Localisable component text based on page language

It would be great to create pages that would share the component layout, but allow to edit text for each component based on language value set externally (one page per language). Not sharing layout per language is not optimal since if a user edits not only the component text, but also the page layout, all pages in other languages must be edited to use the new layout, which is not easily maintainable. Personally, I envision this as component inner text not being propagated to HTML inner text on export, but rather as pairs of component id (or text key) and text values.
