WebP on pixelfed.social

I see there's an update coming soon that will add support for AVIF (woo!) and I wonder if that'll also coincide with enabling WebP for pixelfed.social? I was hoping to use less platform resources by uploading smaller/better files.

Also, if they're smaller maybe they won't have to be reconverted server-side? It'd be nice if I could optimize them locally from RAW without them being reprocessed but didn't see any guidelines in help that would guide me in doing that. Or will it be re-jpg'd regardless of what I send?
