The network layer check is a filter on supported image formats. E.g. both image/png and image/gif MIME types can proceed and will produce a load event. However, if both are for a GIF resource that will only decode with the image/gif MIME type. That distinction would mean it's no longer just something we could check in Fetch. It means the image decoder (which typically handles a bunch of formats) needs to play an active role too. It's not entirely clear to me why it is desirable to be able to enforce a distinction between different image formats. -- https://annevankesteren.nl/
