Indeed, when referencing a URL I don't think progress bars are much of an issue, but when dealing with a local file upload it would be great to have those values exposed to scripts! I hate having to poll the server for a progress update... it's so 1990. Or has this already been exposed to scripts... am I behind the times? So much to keep up with!

I guess it's a matter of preference, but if you're uploading a load of images for instance, it gets tiresome having to keep clicking select file on every new input element. I wasn't aware that IE had implemented multiple file selection inside a single element however I would never have noticed anyway as I shun IE and avoid it like the plague.

If you are uploading by reference to URL (which presumably the server
would fetch to save bandwidth) then progress information is probably
not something that can easily be exposed by the HTML interface.  You
might want to use an out-of-band ajax-style channel with javascript to
show progress instead.

That's been in there since HTML 3.2, I believe, and was implemented by
some browsers (IE 5-8?).  User interface concerns almost always end up
preferring dynamic form behaviors, with variable numbers of input
type=file elements added and removed on an as-needed basis before the
form is submitted.
