VK_KHR_format_feature_flags2 is mostly about define a new 64-bit VkFormatFeatureFlagBits2KHR format feature flag type, as 29 bits of the 32-bit VkFormatFeatureFlagBits are already in use. So all the bits from VkFormatFeatureFlagBits are being replicated, and most of the work here consist on switch to the new flags. From the new (not replicated from VkFormatFeatureFlagBits) flag bits, we don't support VK_FORMAT_FEATURE_2_STORAGE_READ_WITHOUT_FORMAT_BIT_KHR or VK_FORMAT_FEATURE_2_STORAGE_WRITE_WITHOUT_FORMAT_BIT_KHR, as right now we require the format on the shader for doing the read and stores. We use now VK_FORMAT_FEATURE_2_SAMPLED_IMAGE_DEPTH_COMPARISON_BIT_KHR, but only applying it for depth formats.
