I've browsed ITEX and looks like it is not based on OpenVINO.
As for me OpenVINO is completely suitable for such plugin like PluggableDevice for Tensorflow ...
For me it looks like 1 step forward and 1 step backward ...
It is obvious that OpenVINO will benefit from integration with Tensorflow and PyTorch as backend for training.
According to https://github.com/openvinotoolkit/openvino/discussions/16472#discussioncomment-7080385 OpenVINO integrates with PyTorch for training, but at the same time openvino_tensorflow package is abandoned in favor of Intel Extension for TensorFlow (ITEX)
