This seems nice but we'll still likely need preprocessors to aggregate multiple files. The import feature of CSS results in additional, serial requests, which are very not good.

  The networking overhead of serial requests would be reduced by multiplexing in Http2, i.e., multiple http requests/responses can reuse the same tcp connection in parallel...

    I dont think that helps much in this case (or not any more than http/1.1 keep-alive did).
    - la_fayette 5y ago
      Multiplexing is completely different from keep-alive. With http2 a web browser requires one tcp connection per website as communication is in parallel, approaches like conncatenating several css files into one have no use with http2 anymore! Http1 keep-alive allows reusing the same tcp connection for sequential requests/responses only.

        Oh i know, i just don't think it helps in this situation, as waiting on the tcp connection is not the hold up in this situation.

  I dont think server push is a thing anymore, but preload hints (<link rel=preload) might work just as well for this usecase.

sometimes your preprocessor is cat

  or just minify + cat

unless you send different files each request, pretty sure browser caching is still a thing and imports with `preload` links are just fine?

We rally need Web Bundles so we don't have to merge files, but can create a bundle with all the individual files in it that populate the network cache correctly.

This is where standards and bundlers are converging. Move as much syntax to standards as possible to relieve compilers of the duty, use bundlers to do static analysis of dependencies and build optimal packages for the network waterfall.
