 > Another potential approach would be to modify the regex...

 Yeah, looked at that too  but it would be a (hacky) fix on top of another
 hacky fix (parsing HTML with regex) on top of another... :)

 Yet another possible approach would be to not regenerate all the image
 block HTML, just run it through a filter with all the extra image data as
 params. But then a theme or a plugin will still have to regenerate it or
 parse it and replace attributes with regex.

 There is even an option to add the available image data at time of editing
 as attributes to the `<img>` tag and leave it all to themes/plugins to
 handle. Somehow not thinking that'd be good.

 Thinking best would be to take a step back and reevaluate the scope of
 this ticket. We have the time now, it is for WP 5.2 :)
