Why would we remove the _op_translation folder? I think having the folder is better for tracking and maintenance, especially when we start to support more and more versions that ONNX will release.

The folder is invisible to setup.py. Let me see how I can keep the folder while still be able to pack the wheel correctly, I am guessing it's because the underscore?

Yeah, maybe we can try changing the folder name
