This is very important feature. In CKEditor is it a success but the for the Media Entity nothing.... responsive_image or image should have a Figcaption tag with a caption from the image field ... if you add a custom field, its rendered out of the image field.

The HTML 5 attribute longdesc isn't supported:

For clarification, are we talking about a caption or something else? I understand that captions (intended to be seen or heard by all, whether or not they can see the image) and alternative text (intended to be seen or heard only by people who cannot see the image) are two different things, but is description a third thing, that is intended to be seen or heard by content maintainers?
