Comment (by pbiron):

 There are probably a number of ways to address this but my suggestion is:

 1. in
 [[https://developer.wordpress.org/reference/functions/wp_save_image/|wp_save_image()]],
 augment the `_wp_attachment_backup_sizes` postmeta to contain the info in
 the `sizes` portion of the `wp_attachment_metadata` postmeta
 2. in
 [[https://developer.wordpress.org/reference/functions/wp_delete_attachment/|wp_delete_attachment()]],
 use that augmented info to delete the files that are currently not being
 deleted
