I'm all for good compression but tbh it's starting to get ridiculous.
HTML/CSS/JS: prefer brotli, then gzip, then identity (no compression), using the Accept-Encoding header.
Pictures: convert them all to AVIF and WEBP. Keep JPEG around as well for backward compatibility
Other bitmap/non-scalable images: I guess still use PNG unless I missed something
And now SVG, used to be compressible with brotli but soon we'll have to export it to IconVG.
What's next, changing the transport to UDP? Hah!
Oh wait...
