The current proposal has support for quantized types like tensor-quant8-asymm and some operators support them. Many networks run in mixed precision i.e. quantized output matrix multiply followed by logsoftmax in float32.

Propose adding https://github.com/onnx/onnx/blob/master/docs/Operators.md#DequantizeLinear and https://github.com/onnx/onnx/blob/master/docs/Operators.md#QuantizeLinear to make the quantized operators actually usable for many models.
