Chrome and Firefox both have a preloaded list of sites that should always use HSTS. https://blog.mozilla.org/security/2012/11/01/preloading-hsts...

Right but site owners need to request inclusion on that list only after they've enabled HSTS on the server. I've done this myself and I must say I'd be pretty angry if browsers forced an entire TLD to require HSTS. The result would be SSL warnings everywhere.

That's why he's suggesting that the new TLDs do this, to start early, so that everyone's expectations are set properly.

A preload does not require the header to be set. It would obviously be the smart thing to do, but it's not required.

HSTS is only a header.

did you read evilpie's link?

"Only if a host responds with a valid HSTS header with an appropriately large max-age value (currently greater than or equal to 10886400, which is eighteen weeks) do we include it in our list. ... We limit the list to hosts that send a large max-age under the assumption that these sites will not revert to non-HSTS status."

but you obviously can't check every domain in the TLD. A preload will still function, that's the whole point: make sure a MITM can't cut off the HSTS header.
