Ice still has nonexistent defensive utility due to lacking resists (only resists itself) and a ton of weaknesses, including a vulnerability to Stealth Rock in a meta that is looking to be very heavy on hazard stacking. (Boots exists but that means losing out on other potentially better items.) Offensive Ice-type might appreciate dodging a few KOs they wouldn't have otherwise, but I think the overall status of the type will largely depend on how weather interacts with Terastal and, eventually, if we get better hazard removal.
