mltable 'coming soon' clarification on API reference page

Is `mltable` still development? I'm unable to install it (https://github.com/Azure/azureml-examples/issues/1653).

I found this:

mltable (coming soon) - used for Automated ML and Parallel Jobs. This type defines tabular data - for example: schema and subsetting transforms.

from here: https://github.com/Azure/azureml-examples/tree/32cba55f2814c85eee15d990e9ac0ba1a47f96dd/sdk/assets/data#understand-uri_file-and-uri_folder-types

If it's still in development and not yet supported, it would be good to clarify this in the API reference.
