 > All of this sounds pretty good, in theory. I wish we could do that right
 now. The problem is that less than 25% of the websites currently support
 HTTP/2: https://w3techs.com/technologies/details/ce-http2/all/all.

 As I was looking around for what the latest is for `<script module>`
 attribute, I noticed that today (21 months later), "HTTP/2 is used by
 41.7% of all the websites.". That's ca +1%/mo tempo or thereabouts. And
 HTTP/3 QUIC is already knocking on the door.
