How were Experience Fragment language masters intended to be used?
I've seen experience fragments structured with language masters in a couple of places. One would be the documentation here:
In Sites, I can create live copies of my language masters; I don't see that as an option for XFs. One poster on stack overflow suggests that this is not possible:

I haven't checked, but I suspect that the folder data type excludes the properties required to track live copies. Is there really no means to sync an XF to a language master?
Current best practice is to use XFs to normalize site headers and footers. The core XF component assumes page and XF structure mirror each other in order to perform localization, which means I've got at least two footer XFs per language (example: German language master, German in my regional Germany site, German in my regional Swiss site, etc) and no automated way to keep them in sync.
