Who cares? Someone mentions some ideas in an e-mail, of the type "it only takes 10 seconds to invent a new chess variant". It doesn't seem like anyone seriously followed these ideas, by making a preset for it, or even a serious page with a rule description and a diagram. It doesn't seem like anyone ever played it.
So if you want the Giraffe to move as F, and the original idea did not, you now have invented a new chess variant that is just as important as the one described in the link, and you could decide to play that.
