Just wanted to leave a note here, that we need something similar, but not for the alt-text, but for a subset of fields of the media entity to override in the referencing media reference field wiget.
https://www.drupal.org/project/media_library_media_modify β is close, but implements its own field type, which is a problem for existing sites. Instead, it should be a field widget for the existing media references.
