Using a specialization constant as a size of an array placed inside a buffer results in a runtime error

[n9H07]

The following is working:

layout(binding=0)buffer _{mat4 b[52*3];V v[];};

The following compiles successfully but fails at runtime:

layout(constant_id=0)const uint n=52;
layout(binding=0)buffer _{mat4 b[n*3];V v[];};

Error message:

VUID-VkPipelineShaderStageCreateInfo-pSpecializationInfo-06849(ERROR / SPEC):
msgNum: 1132206547 - Validation Error: [ VUID-VkPipelineShaderStageCreateInfo-pSpecializationInfo-06849 ] | MessageID = 0x437c19d3 |
vkCreateComputePipelines(): pCreateInfos[0].stage After specialization was applied, VkShaderModule 0x0[] produces a spirv-val error (stage VK_SHADER_STAGE_COMPUTE_BIT):

The Vulkan spec states: If a shader module identifier is not specified, the shader code used by the pipeline must be valid as described by the Khronos SPIR-V Specification after applying the specializations provided in pSpecializationInfo, if any, and then converting all specialization constants into fixed constants (https://vulkan.lunarg.com/doc/view/1.3.283.0/windows/1.3-extensions/vkspec.html#VUID-VkPipelineShaderStageCreateInfo-pSpecializationInfo-06849)

I have read the specification:

Changing the specialized size will not re-layout the block.

Why not? Isn't spirv meant to replace the traditional method of generating and compiling glsl during runtime?
