 > Is there a reason for this approach, vs the native Chrome approach
 described above?

 Native Chrome approach = Chrome only (https://caniuse.com/#search=loading
 - currently 0.15%)
 lazysizes + native-loading plugin = multiple browsers (lazysizes for those
 that don't support the loading attribute, native for those that do)
