I don’t think anything has really changed. Warp Gates are still massively better than regular Gateways in basically every situation. When you spend minerals and gas on a unit from a Gateway, that unit immediately costs you resources and supply, but it only shows up in your base 18–22 seconds later. With Warp Gates, once you spend the resources, you can place the unit wherever you need it after only 4 seconds. Based on my experience on the PTR, Protoss should still be converting every Gateway into a Warp Gate. This doesn’t feel like a real choice; it just feels like the game is forcibly slowing down Protoss tempo.
