What I have been trying to explain is that it doesn't matter how many parities have a share in a certain property; as long as they all agree and consent to the depiction.

Madame Vastra may be owned by both Moffat, as an individual character, and the BBC within the Paternoster Gang (I don't know for sure at all though). But so far all partities have agreed, consented and licensed all of her appearances - so it has been the same character throughout. No need for a split page. But if Moffat went off on his own and began developing Vastra as his own character - he could do so, and she would become a new character in her own (now with the added limitation of not being able to reference her DWU exploits).

This is the same for Gallifrey / the Homeworld. The licensees may have agreed in the depiction for Lungbarrow but since then Faction Paradox has developed the Homeworld on their own. This fundamentally separates the two.
