Vulkan was always designed to be extremely low level API and with an idea in mind, that libraries would be required to get it up to level of OpenGL/DX11 and others. So in this respect, extensively using libraries on top of it is very normal, just like you don't write your software against syscalls these days.
That's what bothers me though; why not have an official higher level API that's less awful to use? Instead you get a bunch of third party libraries bolted on top of everything.
Why though? Khronos doesn't have the best record of API design and there's plenty of other projects that are much higher level and simpler to use for a newbie developer. You can scroll just a bit up and see just how many webdevs end up using webgpu which is closer to the abstraction they prefer.
