Or, as I stated, for preload, you have to either not have HTTP at all, or have a redirect to HTTPS: it should be clear from my above post why I think a redirect is a bad idea. I also dislike turning off HTTP for those that don't have any other option.
To me it seems that browsers just switching to https-by-default and http-as-fallback is a much simpler, better, backwards-compatible change that should just work. What am I missing and why do you feel HSTS is a good idea compared to that?
