So whenever I'll develop Quxnaṣ (already kind of a proto for most languages of area where it's spoken in my conworld) I'd be glad to nominate it as the ancestor lang, but here arises another question - how much batshit is allowed? Xwarṣa and Ødilaaïffe are totally ok. For more try browsing inactive conlangs, bc there are more complete inactive conlangs than complete active conlangs.
