Browsers can use OS mechanisms *under the hood* if they want, but it's
absolutely the browser's job to expose website-specific privilege
escalation to the user, and it's absolutely the job of designers of
web APIs to design mechanisms to request it.  (For example, a file
input box is a form of requesting privilege escalation.  By selecting
a file, you elevate the page's permissions temporarily to give it
access to that file.)

I'm very certain that HTML5 file access will not be changed to allow
any script to access any file that the OS allows the Javascript engine
to access.
