I'm curious if it is worth it to support AVIFs using next/image, of course next will show the best format for the end-users browser, however with AVIFs they specifically state that typically the first request is slower than other formats and then subsequent requests are served faster from the cache.

My question is, if it serves faster only from the cache is that really an improvement? The cache already serves images very quickly I would think the initial load is more important than the subsequent cached loads.

Curious what your thoughts and experiences are, I used to use AVIF formats but I disabled them because of this without actually knowing if it was negatively impacting my end-users.
