Comment (by azaozz):

 After more discussion in Slack
 (https://wordpress.slack.com/archives/C02SX62S6/p1620500571129800), the
 requirements/expectations for `filesize` seem to be:

 - It will only be added for the "full" image size. This may not be the
 uploaded/original image file if the image was resized on uploading.
 - It may be missing or unreliable (if the image was optimized by a plugin
 after uploading), and will be used primarily as cache when showing image
 info in wp_admin.
 - May be good to have some sort of a "backfill" functionality when
 `filesize` is missing. However that should happen "very sensibly". DB
 writes should be optimized (single write per page load) and happen only
 from wp-admin.
