Debate is scientifically very valuable and it seems that you both know a lot about the topic (certainly more than me). But please keep a professional tone and don't get personal. There's nothing wrong with someone simply because they disagree, especially since the language is resconstructed anyway, so there is no right and wrong, just more plausible and less plausible.
I think you both made fair points, and with the knowledge I have I honestly am unable to decide which is the better option.
Seems right, thanks, I can add it to the PR.
