To me, this is an improvement. I don't care about the thing about preventing people from screenshot-ing tweets, since the barrier was so low it was happening often anyway. But, I've seen many cases of accounts being impersonated and used for scams, where the impersonated user only finds out after the damage has already been done. E.g. you sell commissions for something, impersonator makes an account, blocks you so you can't see him, then tricks potential customers into sending him money. You only piece things together weeks later when those customers start calling you out for running off with their money. Another variation involves someone commissioning something, then blocking when their order is ready as a way to harass the creator.
