Vulkan 1.0 render passes have been replaced by dynamic rendering in 1.2. Blender Vulkan backend was implemented with dynamic rendering in mind. All our supported platforms support dynamic rendering. Render pass support was added to try to work around an issue with legacy drivers. However these drivers also fail with render passes. Using render passes had several limitations (blending and some workbench features were not supported). As no GPU uses it and it is quite some code to support it is better to remove it.
