One of the reasons we decided to go with this approach is no other than SEO. 
Using Client Hints Combined with Service Worker will get you all the performance benefits 
for your end users without the SEO disadvantages that comes with the URL Rewrite.
WHY ITS IMPORTANT NOT TO CHANGE IMAGE URLS
In case you rewrite your image urls into something else all 
SEO juice from all image urls goes to the Vendor domain 
even if the urls contain a canonical name, they are still searchable using the vendor url.
