Not sure if this is an "oh, no" event.
So this goes into Vulkan. Then it has to ship with the OS. Then it has to go into intermediate layers such as WGPU. Which will probably have to support both old and new mode. Then it has to go into renderers. Which will probably have to support both old and new mode. Maybe at the top of the renderer you can't tell if you're in old or new mode, but it will probably leak through. In that case game engines have to know about this. Which will cause churn in game code.
And Apple will do something different, in Metal.
Unreal Engine and Unity have the staffs to handle this, but few others do. The Vulkan-based renderers which use Vulkan concurrency to get performance OpenGL can't deliver are few. Probably only Unreal Engine and Unity really exploit Vulkan properly.
Here's the top level of the Vulkan changes.[1] It doesn't look simple.
(I'm mostly grumbling because the difficulty and churn in Vulkan/WGPU has resulted in three abandoned renderers in Rust land through developer burnout. I'm a user of renderers, and would like them to Just Work.)

it's not.
descriptor sets are realistically never getting deprecated. old code doesn't have to be rewritten if it works. there's no point.
if you're doing bindless (which you most certainly arent if you're still stuck with descriptor sets) this offers a better way of handling that.
if you care to upgrade your descriptor set based path to use heaps, this extension offers a very nice pathway to doing so _without having to even recompile shaders_.
for new/future code, this is a solid improvement.
if you're happy where you are with your renderer, there isn't a need to do anything.
And apparently if you do mobile you stay away from big chunk of dynamic rendering and use Vulkan 1.0 style renderpasses... or you leave performance on the floor (based on guidelines from various mobile GPU vendors)
Vulkan on mobile and web runs several years behind Vulkan on desktop. This is a problem for portable toolkits such as WGPU.
