After my last rant, Larry from Ma.gnolia chimed in, saying that improvements are on the way and indeed they were.
3x less bytes to download, but I believe more importantly - 10 HTTP requests now, 2x less than before. 6kB HTML, only 1 .js file and only 1 .css file. And none of the old functionality is lost. If there is anything lost, I did not use it then.
One could call this perfect. Great work.
