Is Vulkan support considered stable?

I’ve been wondering this based on the docs and blog posts. As of Unity 5.6 which was released last March, Vulkan was listed as one of the new rendering backends for Windows and Android. Is this support considered stable and ready for commercial release?

According to the developers behind Sky Force Reloaded, whose game was the basis for the Vulkan on Android demo in GDC last February, they’re waiting for a release later this year of Unity where Vulkan support is finally considered “officially” supported. Is that not the case right now?

Its exprimental as of 2017.1f3

For example our game crashes as startup when in build mode (SteamVR)
