I wonder if HTTP exchanges / Web Bundles (from the Web Packaging proposal) would bring the approach of statically generating request-response pairs more to the mainstream.

If I understand correctly, then with both hosting and browser support for Web Packaging proposal, one could even statically pregenerate the whole signed exchange or bundle and skip the server-side TLS part as well.

The whole certificate renewal process will probably make that last part nonviable.

Not considering other potential effects on the web if the proposal gets adopted of course.
