Reading through things, I believe what you are trying to do is possible as per
the spec but it requires a bit more care than you have given it.  In
particular, the YCbCr image needs to be created with the
VK_IMAGE_CREATE_EXTENDED_USAGE_BIT and you need to chain in a
VkImageViewUsageCreateInfo struct to vkCreateImageView with the
VK_IMAGE_USAGE_STORAGE_BIT set.  That said, the interaction here between
VK_KHR_maintenance2 and VK_KHR_sampler_ycbcr_conversion is a bit subtle so I'm
not that surprised that both of you (along with the CTS authors) missed it.
