This is actually what project Gutenberg is about in a certain phase (I don’t recall the precise phase). I think it is planned for the coming year in WP?
I see this petition has a status of duplicate.
This is the original GitHub · Where software is built, I can’t find that in the forums, but I could find Solid Solution For Multilanguage - Polylang + Codestyling L, and Internationalisation of ClassicPress, which seem related (but are not petitions)
Does anyone know where this duplicate is?
The topic is interesting at least, also because we need to consider this with relationships (at least prepare for it somehow while doing it)
