Without HSTS, you can inspect the cert and click through the invalid certificate warning.
With HSTS, that button goes away in browsers.
In the example you gave, wouldn't you have lost all your work anyway without HSTS? I don't think browsers supply an easy way to retry POST to the corresponding http: URL whether HSTS is set up or not.
