Some of the features provided by extensions are not checked if they are supported or not on the device.
If for example the feature Float16Int8Features.shaderFloat16 is requested, but it's not supported by the device, Amber doesn't print any meaningful message. The vkCreateDevice will just fail and Amber doesn't tell any reason why it failed.
All of the device features listed in amber_script.md should be checked if they are supported when they are requested:
