Currently we can include alt text in image settings. I would suggest we could do also in images in the background of other elements like div.
A background image is technically a "style" so you'll have to set a custom attribute for "title" for search engines to treat that element in a special way. Image attached of an example (you can do this at the bottom of your element settings).

With global ALT text definable site-wide within the asset panel, can we have an option to have this ALT text automatically apply as a 'title' attribute in circumstances when used as a background image and option to manually override per DIV attribute, just as we can do today with ALT text per image?
How do we prove is this approach actually works? Is there a new way to solve this issue to add alt text to background images?
Does it matter if the attribute says "title" vs "alt text" to make this work?
Yes, I agree. All of my images are as background within a section.
The image area allows you to edit everything, except alt tag. *cry*
