Hello, Ofer,
We have a specific TextArea component planned for this quarter and it will have some of the TextAreaAutoSize features.
As for the Upload, it has a custom item rendering for the file list, and we can use it to render a text area for each file:

If you share more details on how this should look and functions, we can provide more to the point example and/or suggest if a new feature will be required.
Regards,
Stefan
