Context-related metadata in sys_file_reference?

[wowaTYPO3]

In order to maximize accessibility, the alternative text of an image should always refer to the context in which the image is used. The same image can have different alternative texts, depending on the context.

It would therefore be cool if the texts could also be created in the file references in content elements. Then, of course, all texts on the respective page would have to be taken into account.
