Segwit is not necessary if you have block time of 4m and block size of 2 mb ...
Without segwit it will only have 5 times the tps bitcoin offers(worse than zcash), will work initially but not long term.
I do not get any good feelings from this project. But best of luck anyway.
That is justified, it's experimental and no developer yet(i have not time to learn that shit atm).
