Lol one of the top three altcoin developers. Gulden added a new diff retarget algorithm so he's a top three developer? Satoshi, Nic Saberhagen, and MaNI...Riiiiiiiiiight

Besides, segwit has additional benefits besides extra block space - eliminating malleability which I think makes implementation of payment channels/lightning easier for instant payments, easier integration of side chains, and easier cross chain transactions. I'm not saying it's a great idea or not, but even if it never activates on Bitcoin it still might be good as then Litecoin would have some distinguishing feature.
