Google has already achieved this goal with their QUIC based HTTP/3. No implementation or use of HTTP/3 lib in any browser can connect to a webserver unless it gets the continued approval of a third party incorporated CA for TLS certs. With a 90 day renewal period that's basically just attestation of content every 90 days. If your site becomes illegal in an area (say, abortion information) then your CA TLS host can be pressured, cert revoked, and your site made unvisitable for all but uber geeks compiling their own HTTP/3 libs with special flags and linking them to $browser manually. There's no way to host a HTTP HTTP/3 site that's visitable. And no one minds. So...
Google could have avoided all of this blowback over WEI by simply calling it "HTTPS+ Everywhere" and pretending it helped user privacy only.
I'll grant there are a few more TLS CA options than possible WEI attestation options (if they really are to come from the OS vendors like the spec suggests). But not that many more and any legal pressure applicable to one is applicable to all. Both Google WEI and Google QUIC HTTP/3 are terrible and both need opposition or at least mitigation.
